I tend not to watch too many anime I don't think 
I'll like.  Here are a few I caught though...

1) G Gundam: Undead mummy gundam.  Sure....

2) End of Eva:  I liked most of the TV series, 
though the last two episodes I think were 
annoying.  End of Eva was the most pretentious 
thing I have ever watched.

3) Kite: I happened to unknowingly watch the 
uncut version, which completly turned me off.  
Who really wants to see an old ugly freak guy 
raping a young girl and then killing her?

And a more common occurence... series that didn't 
live up to the hype for me.

1) Kenshin TV:  The background music seems very 
inappropriate at times, and the jump between 
comedic and dramatic moments is very jarring and 
not nearly as well done as a lot of other series 
(Trigun, IY, FY...)

2) Cowboy Bebop:  If you are going to run a show 
for 26 episodes, you might want to do more with 
the main character than have him continue the 
downward spiral he started way before the show 
did.  And Julia was a horrific case of character 
abuse that really actually did little to affect 
the plot.

3) Escaflowne TV:  I thought most of the 
characters could have been fleshed out a lot 
more, and some of the events at the end were just 
so bizzare/silly that I had trouble taking 
everything that had happened before seriously.  
See, didn't mention the noses.
