Underrated Masterpiece. One of the best horror movies of all time

I'm a horror buff, but Very few American horror movies in the past 10-15 years have really wowed me, but this one did

The main characters were all fairly smart, which is pretty rare in horror movies. It's a common tactic in horror movies to dumb down the characters so that they can put themselves in dangerous situations. So kudos to the writers for not taking the easy approach. I liked how the outlaw and the hot girl used a scooper to slide the lighter fluid under the closed door so as not to risk getting attacked

The acting was good, especially that of Shea Whigham, who should have gotten a much bigger career boost from this film because he's a real badass

Also, the concept is fairly original and intriguing. The "monster" itself is just a simple, multicellular mold-like spiky organism. But the fact that it uses corpses and limbs for mobility gives it a very disturbing and grotesque appearance, especially when it sows multiple bodies together

The only real problem I had with the movie was the camerawork. It's hard to tell how exactly the monster kills its victims. Mainly you just see it shooting splints or flailing itself towards its prey and in the next shot the person is dead. It doesn't seem to bite, stab, or bludgeon it's victims, yet the deaths are very quick.

In summary, I think Splinter is an underrated horror classic. It should have spawned a franchise and turned the writers, the director, and Shea Whigham into stars.
