Hmm... I watch anime, I was quite the otaku at one time.
I Prefer Subbed Anime but, there are few series I like better Dubbed.
I think that My Absolute Favorite Series By A Very Long Shot and Of All Time or at least until I see one I like more... IS... Code Geass R1 and R2. Especially R2. I even named my Gamertag after R2.
My favorite Genres are Comedy, Action-Adventure, Drama, Science Fiction, and Mecha
The Series I watched most recently is Tengen Toppa Gurren Lagann which has to be my second favorite.
Genres are Mecha, Action, Adventure and Comedy-Drama
I give the Series a 9.5 out of ten. I only took the .5 off because of the extremely cheesy Mecha battles which aren't bad but seemingly impossible things happen during them which is what I didn't like. i.e. weapons appearing from no where etc.
A few other Animes I liked:
Naruto and Naruto Shippuuden (one of my favorites)
Bleach (one of my favorites)
OutLaw Star (my favorite older anime)
Death Note ( I only Liked the 1st half, I kinda lost track not long after. But the last few episodes were epic!)
School Rumble (I liked season 2 the best)
(All) Full Metal Panic!
Melancholy of Suzumiya Haruhi (seemed incomplete)
Clannad and Clannad AfterStory
Lucky Star (I liked the hilarious "Lucky Channel" bit at the end of each episode the most)
Etc. I couldn't name all the ones I liked even if I tried
I switched to Naruto and Bleach Manga because I got tired of filler.
