I was pleasantly surprised by the new Star Trek movie last night. [Some spoilers to come.]
As a prequel to the original series, it could have been dire. Instead, all the familiar characters were beautifully played without ever being a caricature or impersonation of the original. Chekov, for instance, had all his youthful enthusiasm - but had lost the dire hairstyle, introduced to try to win over fans of the Monkees. I particularly warmed to McCoy - it was no surprise there was a small cheer in the cinema when we got 'I'm a doctor, not a physicist' - but they were all excellent, Simon Pegg proving a much better comedy Scotsman than the original.
Some aspects were a bit iffy - the whole red matter/black hole business, for instance. (Including the way the crew happily sat by as a black hole formed, then were surprised it was difficult to get away. Duh.) But not too many.
Perhaps most controversial was setting it in an alternate reality to the original series. This meant a slight feeling of detachment - these weren't 'our' characters, really. But it was an essential for the writers. Otherwise we would know, for instance, that Spock's mother couldn't stay killed, because we saw her in Season 2 of the original series.
All in all, it should delight any Star Trek fan, or even those with faint fond memories, and works well as a new version of the franchise in its own right. There's bound to be another, and that's not a bad thing.
