Deliberately plain, dumb and violent fun.

I am never quite sure where to draw the line between a bad movie and an ode to a bad movie. But I am sure there's some ok fun and slashing to be had here.

Somehow it didn't really work.

It's a vibrant, original, good looking adventure with plenty of good jokes... yet still it doesn't quite take off. Something flat and distant remains, and maybe relating to turkeys in a time machine is just a bit too much to ask.

Genuinely scary and expertly done

A really scary movie with agonizing tension built-up courtesy of great camerawork, a slow but deadly script and effective and sober use of sounds. I'd say it was a bit too long though. The finale is suitably terrifying, but by then I felt a bit saturated.

One hell of a scary movie!

An excellent adaptation of the standard "creepy demon in a house" plot, that will scare the **** out of you. Sound effects and background music perfectly add to the suspense..

Great prehistoric graphics and fun

Not overly successful in setting up characters you start to love, but beautifully rendered, quite exciting and good for a few laughs. I deduction half a point because it failed to make a lasting impression on my kids.

Surprisingly boring

Despite colorful characters and a potentially funny story, this movie is remarkably boring, and the Tim Burtonesque overacting and pacing got on my nerves here. Partially saved by a delightful Eva Green and a reasonable climax.
