Following it is alright, I myself follow the French championship even though it's shit. But I don't actually watch the games, I have too much self-esteem for that.
I watch Real Madrid and Barca games, Premier League big games (Man U - Liverpool, Chelsea - Arsenal and the likes..), and of course the Champions League. And that's it. That way, I'm (almost) sure to watch quality football.
I also watch the national team games, despite their atrociousness. And Euros and World Cups, but that goes without saying.
edit: Anyway, my point is, if you have to waste an hour and a half watching a game, make it a good one. Don't you agree ?
