I am a fan of Star Trek. I've watched most episodes of all the series (especially Star Trek: the Next Generation, and not counting Star Trek: Enterprise), I've seen the movies, I can even tell you how Captain Picard likes his tea.

I watched Star Trek Into Darkness, and I liked it. It certainly has its flaws, but overall I quite enjoyed it.

However, there seem to be purists who consider it one of the worst Star Trek movies ever, maybe even worse than Star Trek V: The Final Frontier.

What are some Star Trek-related reasons that a Star Trek fan would rank this film near the bottom of the list of Star Trek films?

This is not meant to imply that only a Trekkie could hate the movie nor that a Trekkie could only hate it for Trek-related reasons. I am just curious about the phenomenon of Trekkies hating it for Trek-related reasons.
