Just got back from the cinema...
I must say I was very impressed, I think Snyder done a fantastic job not to mention the stewardship and guidance he had from Nolan.
Henry Cavill does a superb job playing the role, as does Michael Shannon play playing general zod.
The fight scenes are truly epic, it's the first film I've seen that truly depicts super human or god like powers in a way that we can perceive as real or remotely believable. Supporting actors also provide a sterling job, most importantly those of Costner, fishburne and especially Crowe.
My only criticisms would be of Amy Adams potrayal of Lois Lane and Clark Kent's character development. I think Adams has been recruited on this film given her recent successes with other movies but it doesn't translate to man of steel. Also the whole development of Clark Kent from small boy to fully fledged superman is quite quick, there is not a lot of self discovery and the film leaves the audience coming to a lot of conclusions themselves.
All in all though a sterling film, me and my girlfriend thoroughly enjoyed it and would reccomend it without a problem.
Stevie.
