Pretty good if you can get past a few issues ... spoilers to follow

My biggest complaint was the parents being complete morons in the opening scene. They let the little kid, who had minutes before almost killed them b/c he was left on his own, stay behind to do whatever. Then they have that little moron guard the rear or something with fairly predictable results. I guess the even more predictable outcome would have been for someone else to get killed saving the kid, leaving him to get someone else killed later, so I guess I should just be thankful he was finished off early.

I still liked it though.
