0-0 matches can be good though, it's not at all as uncommon as people genereally think to be fair. The most recent I can think of is Arsenal-Liverpool, one of the more entertaining matches I've watched this season.
Anyway, I've never really been a fan of the 4-3s/5-4s of the game, I think it's usually just a shambles with far more mistakes than good performances, so I'd argue quite a few of them are overrated.
