1. Now and then one character accuses another of glorifying violence, 'that brute vigilante junk.' Talk about hypocrisy: Without the brute vigilante junk, this 82-minute picture would be approximately 2 minutes long.
2. The story's nothing special, but the movie is vigorously directed, with a camera that moves at a decidedly un-turtle-like pace. And the animation is unusually handsome.
3. It's a delight to report that the return of the brawlin' reptiles lives up to and surpasses even the most potent expectations.
4. It has a dreadful Ghostbusters-Stargate plot, virtually no decent jokes, but toss in a little digital skateboarding, a lot of digital swordfighting (gunplay, too), a couple of 'Cowabungas,' and you've got yourself a hit. They hope.
5. What's lacking, except in too-quick flashes, are some of the subtler spices -- wit, self-mockery -- strewn through this franchise in all its various formats.
6. The unexpectedly rich art direction gives the violence more impact than was ever possible in the TV series.
7. 300 for kindergarteners.
8. The preteen fanboy in me kept searching for something truly exciting in this movie, but, sadly, the critic in me knew that it wasn't there.
9. This is no mythic rebirth like Batman Begins or Superman Returns, simply another generically smart-alecky chapter directed with a visual style attuned to speed.
10. The real power in the TMNT stories is the transformation, but in this movie that's all in the past, and it is difficult to get much satisfaction from the comeback premise or the attempts to create some sibling rivalry. It's more video game than story.

What is a brief summary of the following reviews?
TMNT's art direction is splendid, but the plot is non-existent and the dialogue lacks the irony and goofy wit of the earlier TMNT movies.
