Why do people keep praising the original so much?
The original was overrated, chock full of cliches. I can recommend several much better foreign thrillers:
1. The Hidden Face (do not watch trailer b/c it reveals the shocking twist)
2. Sleep Tight
3. Tell No One
4. With A Friend Like Harry
5. Head-On
All of these are much better and less predictable; especially "The Hidden Face" which contains probably the most-surprising twist I've ever seen.
