I hate to condemn, but...

1. Record of Lodoss War TV series. The best part 
about it was the opening credits. I can't 
believe I watched the whole thing! 

2. Brainpower'd. I went from "What?" to "Who 
cares?" in about 3 episodes. It's a shame 
because the soundtrack rocks!

3. X/1999 the movie. Made no sense to me, but 
pretty, pretty eye candy.

There are some series that I lost interest along 
the way (Trigun is one, but I think the payoff 
at the end is worth ALL the filler episodes). 

Kenshin also started to bore me with its 
repetitiveness, but I like the artwork.
