Into Darkness was popcorn/bubble gum (leave your brain out your head) thrill ride.
I personally had some issues with it, it was fun ride.
However, it took some serious liberties if the entire universe was suppose to be a variant of the old one but still considered to be canon. Aside from the technology being too advanced at time period they were in, Into Darkness had Khan and before Kirk even found the guy. Klingons weren't made into human like versions that Federation, which hadn't really seen what Klingons look like. Again, that different take. Personally, if they just said it's was imagining/reboot of the franchise verse a alternate timeline. I would had been cool with the changes except for Kirk going from Cadet to Captain in matter of months.
I think though my biggest problem with this film was it was big remake of Star Trek II and not trying to do more original with it. Also the Starship battles were confusing and hard to follow too so it wasn't enjoyable to me. :-X
