FIFA Street is brilliant. Controls are easy to pick up, nothing wrong with them at all. Commentary is bad, yes, but were you really expecting some serious commentary from John Motson or something? The commentary suits the game well. If you don't like it, turn it off.
If you mean no point to the game at all, then you obviously don't like ANY sports games. Just like in any other sports games you play to win games. FS has a great season(Rule The Street) mode, very entertaining.
Great multiplayer, great single player, great game.
