1. Plumbing mishap was dumb and silly.Where did the water go where his body appeared?
2. The Cave of Coincidence could be explained with simple additions in later movies (this is JJ’s style on Lost, anyway—making something look too coincidental to be realistic, then showing how it makes sense in later seasons). All it would take is the marooned Spock to go to the same cave he knew Kirk would go to. How would he know this? Maybe it’s a consequence of a Vulcan—a being who can read minds—being in the same timeline with his past self. A sort of freaky time paradox specifically arising for telepathic beings. Maybe he “remembered” his past actions for this timeline as soon as he entered this timeline—as well as remembered his previuos timeline. Paradox instead of coincidence.
3. I don’t know who Tyler Perry is; didn’t even notice him.
4. Wynona was an odd choice. Not a deal breaker.
5. Red matter was clearly a plot device, and not very plausible. It happens in sci-fi. Were you expecting “hard” s.f?
6. Green girl didn’t bother me. I just don’t get people who complain about girls in their underwear—no matter what their skin color.

7. Scotty’s sidekick was ridiculous.
8. Spock’s chat with himself was one of my favorite parts of the movie. It shows he is trying to repair the damage (kind of like Theomach) and make this timeline as close to the old one as possible. The advice he gives to himself is perfectly in line with his character and what Spock has been through in the previous films as he learns to embrace both sides of his nature.
9. Eric Bana was meh.
10. I liked the Enterprise.
