I thought this turned out decent, I'd say the best way to describe it, is the first bit is a bit meh, but stick with it, then the remaining 2 hours or whatever, were decent good fun, with a good cast.
Although I prefer the original series and the first film, they've come along way since Ghost Protocol! 2/3 were accepted as more action packed laid back sillier sequel style versions but GP tried to step it up and make it serious again as was very hit or miss, I did enjoy the 2 before DR though!
I think 1 is the GOAT, and the perfect balance in every sense, wicked for it's time.
