Not the best game in the world but i've seen so much worse!
The main being it's just plain good fun.
It doesn't need you to try to hard to do anything complex, the combo's are straight forward, the baddies are not to hard to kill and the storyline is not so hard to understand that your brain pours out your ear with confusion, all in all as far as movie based games go this is one of the best, definitely for Marvel (Spiderman 3, Fantastic 4 etc. OUCH!)
This game is a game worth getting for anyone who is a fan of the film (it is not based on the film but has its own storyline, that is in fact better than the film itself) or for anyone who likes hacking style games, who have nothing else to play (personally I'd get the God Of War's first as it's a similar style game, but so much more gory!)
The main flaw with this game is the levels involving the Hell-Cycle they start of fun, but oh my good god they get so dull you could fall asleep.
Also the upgrade system could also use an upgrade itself.
In shot it's not the best game in the world but I've seen so much worse
