Suggest a good anime to watch

Blood+ ? I think it is not popular enough.
Also Cowboy Bebop, Samurai Champloo

Maybe "Kaze no Stigma" or "Black Blood Brothers" ?? :D

First we must start with the most important question: subbed or dubbed? Not asking for a debate on which is better (both have their places) but there's a lot more available subbed only. Second question is would you be ok with things currently airing or some finished stuff you can binge?

mondaijitachi ga isekai kara kuru sou desuyo?

or

umineko no naku koro ni

are pretty good IMO, although they both have their bad points

Samurai Champloo

Again with this topic? I recommend you check past forum threads for suggestions. There are tons of them.

Probably would be helpful stating your preference of genre.

Shingeki No Kyojin :). lots of "fun"
