After having read this topic, I went into flashback mode and had several flashbacks of watching (what little) anime I've seen since I was a freshman in college (excluding a few shows I watched on TV in Korea when I was little). I will now proceed to give a grade to every anime I have ever watched...
Dragonball Z
Grade: B-
Manga was great...much more condensed than the TV version. Pretty good story, likeable characters, memorable villains, etc. Bad stuff: poor animation quality (several hundred episodes...understandable I suppose), bad voice acting (even Japanese voice acting was subpar in my opinion), long drawn out fight sequences. A classic by all means, but not great. One of my first, though.
Kenshin (TV)
Grade: B
Some of the story arcs were pretty good, but I was bored to death by most of them. The fight sequences were always interesting, but also long and drawn out like DBZ. Nonetheless, a classic. Major downfall: Length! I would've given this one a B+ or A- had it been condensed into maybe 1/3 of the episodes that it actually had.
Berserk
Grade: A-
Awesome (and horrifying) story, pretty good animation, memorable characters. Heard the manga is much better, but I haven't had the chance to get around to that yet. I felt slightly cheated by the ending, and some of it was just too disturbing, so the grade falls a bit (but not due to its own fault). If you're in the mood for something serious and brooding, this is it! (Also, very violent)
Slayers
Grade: C
Seemed very average and generic to me...probably would've liked it better as a kid. But then again, heard it's a classic.
Excel Saga
Grade: B-
Manga was pretty good, anime was also good for the first few episodes, then it seemed to lose focus (and budget). The animation became sloppier, and the story became weirder towards the end. No solid conclusion, just kinda let the story hang (which the manga does not).
Too many cultural references to fully enjoy it.
Ninja Scroll
Grade: F
I don't even need to explain myself with this one. BLEH!
Cowboy Bebop
Grade: A+
No explanation necessary here either. Great style, great music, great animation, great characters, great ending, gogo space cowboy!
Irresponsible Captain Tylor
Grade: B+
Enjoyable, funny, sometimes serious. Reminded me of Nadesico...at first, I thought it was just a generic space battleship type anime. But this one proved me wrong...at the end it left a smile on my face (and a desire to watch the OVAs, which were okay but nothing spectacular). A generally pleasant experience.
Nadesico
Grade: A
One of the best space battleship animes I've ever watched...rated in Japan as #1 (I forgot which year). Movie was good also.
Vandread
Grade: Season 1 - B, Season 2 - A-
Another space battleship anime, albeit with a twist. The not so vague sexual innuendo was hilarious, and the story became noticably better towards the 2nd season. First season was okay as an intro, but seemed to exist solely for the 2nd season to shine.
Onegai Teacher
Grade: B
Pleasant story, a bit ecchi though. I've always liked hot teachers (wish I had had one myself), so this is probably biased. The background was very unconvincing though, and some of the anime was just to sugary for my tastes. Touching in the end, though. OVA was purely fan service.
Kodocha
Grade: B+
Insanely funny, super cracked out anime! Lost steam during the later episodes though. Gotta love that mom and the squirrel...
Inuyasha
Grade: B+
Long...but good. I suppose the length detracts from this one as well... since I felt the first season was better compared to the later ones. Maybe I just lack the stamina required to watch an anime that's several seasons long.
Lupin (Castle of Cagliostro)
Grade: A-
At first I thought, ewww what is this? Then towards the end I was like...I LOVE IT! A great classic (just reminds me of the 80s).
Ah My Goddess
Grade: C+
I felt this was just a generic young boy fantasy anime. Characters were well defined, though.
3x3 Eyes
Grade: C+
One of my first...but looking back, it was nothing special.
Video Girl Ai
Grade: B+
Touching, funny, short but sweet. Unnecessary ecchi at times, as well as somethings being too sugary
Sakura Diaries
Grade: B
I thought it was a little hentai-ish, but overall touching story. Characters are likeable as well as fairly well defined. The background was a little hard to believe, though. Guess stripping for a cousin just to cheer them up is fairly common in Japan... -_-;;;
Pokemon
Grade: D
I choose......Bleh!
Bubblegum Crisis
Grade: B-
One of my first...not too bad. My standards just got higher over the years...
Mazinger Z
Grade: A
My mom tells me I practically wet my pants whenever this was on TV when I was a toddler. Special grade just for that!
Love Hina
Grade: B+
Sweet, cute, and funny. The OVAs were horrible, though. Nothing but fan service...
Goldenboy
Grade: B
Funny, but hentai-ish. This was one anime that I actually liked the English dub hehe.
Escaflowne
Grade: A-
Great story, good animation, nice music, just plain cool (and touching). Didn't like the ending or the movie that much. I also got annoyed with all the talk of sempai -_-^
Hellsing
Grade: B
This one was so great in the beginning, then became very disappointing towards the end. The lead character is just too cool, though. As is the priest.
Trigun
Grade: A
Funny towards the beginning, serious towards the end. Explores some deep human emotions as well as being gun-action and not too serious with itself. Loved the western theme...
FLCL
Grade: B+
Great animation, very cool, but a little too weird for me. I know tons of people would give this an A though.
Jin Roh
Grade: A+
Touching, deep, great ending. This one literally sucked me in and spit me out at the end. I was left feeling void of all emotions cause the DVD had taken all of it!
Akira
Grade: B+
Good animation, weird but moving story. Ending was hard to understand, though. Maybe I shouldn't even try...
Evangelion
Grade: A-
I really enjoyed this one, until the end. The ending episodes I enjoyed more the second time around, but I had a hard time relating to all the angst that I felt in this series. The movie was okay but troubling at times. This is one anime that people love to hate, and also love to love.
Karekano
Grade: A
I got made fun of as a sissy for this one, but I loved it! Manga is even BETTER!
Macross, Do You Remember Love
Grade: C
Ahahahahaha! Hahahahahaha!
Vampire Hunter D (old/new)
Grade: A-
Cool lead character, great animation, lovely fight scenes. Not much substance, though.
Hand Maid May
Grade: C+
Bleh....just more fan service. Although it was kinda cute, and funny, and pleasant at times.
Ghost in the Shell
Grade: B-
O.V.E.R.R.A.T.E.D.
Mononoke Hime
Grade: A-
Beautiful...
I might've left a few things out...man I'm tired. Gotta stop here -_-
