Oh yeah, no disagreement there, but the ones I noticed were at the beginning and very end (a big one, but I don't want to spoil it for anyone - if you've seen it you know what I mean), and didn't detract from the heart of the movie. The vast majority of the film was just edge of seat scary. I was rooting for the aliens (my 'Root for Chuckie/Jason' ploy), but this only helped for the first 30 minutes or so. After that Spielberg had me.
