First, if you haven't seen "Oh! Edo Rocket," drop everything, get it and watch it.
IMHO it is the best thing since Cowboy Bebop and Samurai Champloo.  The only three
shows in recent years that have enough grab for me to want to watch them again,
almost immediately after the first time. 

It's non-standard, very original and is wildly different:

I really disliked only one thing in it (half of one episode), loved everything else.



> 1. Hayate no Gotoku!  
Mildly Enjoyed it, but only managed to watch about 1/4 of it.

> 3. Pumpkin Scissors 
Liked it.

> 7. Zero no Tsukaima
First Season: Cute
Second Season: Annoying, stopped watching
Third Season: Friend says is much better than second season.

> 9. Hyakko
Really liked the first episode (funny), but only watched it 3 days ago.

> 10. Kannagi 
Liked the first 3 eps.  Kind of like a mild Aa!Megamisama.
