Excessive repetition...fans will probably like it, stay away if not.
Co-op play is available but there is really not that much to actually do together, its primarily just fighting.
The controls are easy enough but loading the omnitrix is a pain as you have to load one, back out, then go back in again and so on, until you have the four you want loaded in there.
Pro's - It does look good on the big screen with very vibrant colours.
Con's - Boring, un-challenging, repetitive, no replay factor, co-op gets boring quick.
