Well I just listened to the Empire podcast because they talked about Star Trek Into Darkness (spoiler free). They said in summary:
Yes it is very good! Yes there are lens flares! Stunning in IMAX. Some of the 3D is distracting because it is a 2D conversion. Not JJs ESB (if that means anything?!) Not perfect. Feels 'trekkier' than the first one, they say it is more of traditional Star Trek film than the first one. It gets 'twisted by its own logic'. Benedict Cumberbatch is 'absolutely amazing' and 'steals the film' but his plan is 'like Skyfall and doesn't make a lot of sense'. Zoe Saldana gets a lot of the humorous parts/lines. Star Wars in a safe pair of hands. Star Trek fans will like Into Darkness because of all the nods to the original series/movies. Dreadnought is a phenomenal ship. Cumberbatch dominates every scene he is in. 4 out of 5. Very good indeed.
