This movie really impressed me. I found myself enjoying every minute of it. The gender role reversal of Jill Wagner and Paulo Costanzo, whom I haven't seen since Road Trip (2000), and their interaction as boyfriend and girlfriend was not only believable, but compelling--that is, I thoroughly enjoyed every moment they interacted with one another. The relationship was real, and having Jill Wagner as the more aggressive, masculine of the two (Paulo basically played the same brainiac character from Road Trip) was a great idea. Jill Wagner is the girl who hosted the recent TV show Wipeout, in case you were wondering.
If you're in the mood to be entertained, I recommend this movie. In fact, you don't even have to worry about "wasting money" if you have a Netflix account; Splinter is available for instant viewing! Seriously, the film doesn't waste a moment on screen. Every shot, every word, adds to the film's delivery. And on top of the acting, a surprising amount of gritty gore is thrown in! It's amazing what was pulled off in the low-budget horror flick.
The best line from the movie is Jill Wagner's reassurance to the fugitive: "It's okay; we're cutting your arm off."
(P.S. I know I didn't mention anything about Shea Whigham.)
