For past years, I have seen some bad, and confusing 
animes before.  And I wanted to see what your lists 
are. 

Remember, these are just my opinion, no need for 
flaming here.  

1. Akira- -_-  I never understood the anime, the weird 
and annoying music and god....characters are really 
ugly...especially when it goes last part...Overall, 
storyline was ok..but God..I hated the Damn background 
music...Just Hated that Music~

2. Hack/sign-  seriously,  this is first anime that I 
stopped watching after halfway into episode 2...didn't 
bother watching rest.

3.  Excel Saga...just weird...
