Can't agree with the review
I'm a 30 year old who enjoyed watching repeats of the original series but had no time for the Patrick Stewart version. I really enjoyed the first film and marginally preferred it over the second. I've probably seen a couple of the original Shatner movies but I would certainly not describe myself as a fanboy. Khan was a completely new character to me and so I just enjoyed the movie. I didn't go to watch Into Darkness with any baggage, other than having recently rewatched the first movie.
So if you go into a movie with expectations (baggage) then you have far more potential for disappointment. But if like me you're just looking for some entertainment and escapism, you won't be disappointed.
8/10
