I couldn't care less about the name of the planet -- it could be Earth for all I care. It's the entire storyline that took place between Kirk getting stranded on Delta Vega and him beaming out that's stupid.
Rest of the movie? Not as good as Expendables. Better than Speed II. I'll watch it, though.
Huh? Kirk gets chases by some creatures. Gets rescued by OldSpock. Finds out about Nero and how OldSpock got to the past. Gets a little pep talk from OldSpock. Meets Scotty who with a little help OldSpock get them back to the Enterprise.
Not seeing the "stupid".
