Before I say anything:
1. I am a life long Trekkie
2. I LOVED Star Trek (2009) and felt it was faithful to the spirit of Star Trek
3. For a summer blockbuster, I am easy to please
... STID is horrifically and aggressively bad. After a strong first 1/4th, it takes a nosedive into some pretty hammy and cheesy storytelling. I'm not going to go into too much detail, but the entire movie was one long string of "trekisms" being shoehorned in (i.e. this is where you're supposed to yell "KHAAAAN!!!!").
1.5/5 stars. Ya... really. My hopes were high, but now they are dashed
