Saw this yesterday. Not bad at all; although shaky-cammed from start to finish if that bothers you. My only real quibble was how utterly dire the aliens' tactics were, along with the whole "have a whole attack plan based on the operation of one single location, the failure of which causes all the bad guys to shut down" deus ex machina that was used in ID4. As if the alien military would be set up in such a stupid manner that a single little missile could wipe out their entire invasion force! Decentralization, people!
