Difficult to Master
Over the top combat
Characters all feel unique

The Bad:
Steam Version doesn't cross-play in Ranked mode (Works fine for Casuals and Lobbies)

The Ugly:
Rash :D

As far as fighting games go it really is one of the best. Give it a try and don't give up! C-C-C-Combo Breaker!!!!! Pure 10 outta 10 material!
