Man looks like real slim pickings at the cinema lately. This is probably one of the more recent somewhat high profile ones. CGI looks like pure ass though, and overabundance of it. Even Jurassic Park's CGI from 1993 looks a thousand fold better than what I saw in the trailers, and if you're trying to hype your flick on the special effects, it better be damned good not something that looks like it was done by a pre schooler.
And the storyline? Pure cliche, all the way from the schtick about the "chosen one" to the cheesy battle scenes where the chosen one gives an 'inspiring' speech to rally the troops as they all raise their clubs and roar.
Still might be worth checking out.
