Well, we went and saw Constantine this evening. It wasn’t a bad movie, but wasn’t the greatest either. 
I guess it’s safe to say that it’s one of those movies that are worth seeing at least once… but if you don’t get the chance, don’t worry about it.
Though, doesn’t Keanu Reeves get tired of playing the same role over and over again? The lone warrior, out to save the world from all that is bad. Let’s see here, how many movies has he done this in? The Matrix Trilogy, Constantine, Johnny Mnemonic, any others? I don’t guess Bill & Ted count since he was part of a “team” in that one… oh well… time for bed. :p
