Watch Streaming Anime Online Free - English Subbed & Dubbed Episodes

Lately I've read every where about animes that I haven't see

Some of them were old others were new.
But the point is that I din't know them at all.
What I want is you to recommend me some important classic animes (mostly action) .

New anime episodes-seasons questions.

1st question: Will there be a new season of H.O.T.D.?

2nd question: What will happen with D-Gray man, the episodes suddenly stopped while the manga continued. Will they continue the anime?

3rd question: Any thoughts about what's going to happen to Fairy Tail manga?
