Star Trek (2009)
the movies are now in an alternate timeline from the series
I reckon it's mostly this. Although it's entirely possible later events (such as the crew's meeting with Lucifer at the centre of the galaxy or TNG, DS9 and Voyager) will happen, it may not happen in exactly the same way. I can't remember how much Starfleet training they said Kirk received in the new film, but they've changed his past now.
I do agree with what you said about Pine's Kirk impression, I felt his mannerisms were spot-on
In Groundhog Day he always wakes up in the same day. In 50 First Dates the girl has a medical condition that causes memory loss when she goes to sleep. Every day when she wakes up she thinks she's living the day in which she had the accident.
Oh, so it's like Groundhog Day, but in reverse
