Didn't plan on seeing it but my mate paid for me as he didn't wanna go alone.
It's a pretty mediocre action film and the script is an atrocity but the actual production was very solid. Really liked the cast (With the obvious exception of Alice Eve!), special effects and the opening sequences. Nothing could raise the film above its script though.
I have no idea why Khan was even in this movie, or why the writers felt so lazy as to just rehash surface beats from Star Trek II. Instead of taking important stuff (Like the depth surrounding getting old!), they just took a bunch of famous lines and used them in increasingly cheesy ways. Quinto's "Khaaaaaan!" being the lowpoint of the film.
A solid C-. Fun, noisy, dumb entertainment.
I don't belive that you didn't pay for it.
