You have to take online reviews with a grain of salt. S. Darko was a day one purchase for me. It wasn't even close to the original, but it was still a decent flick.
Just watched both Sherlock Holmes movies, both are kind of entertaining, but the first one was definitely better.
Decent entertainment if you have spare time, but not a must-see
The full Rambo collection.
If you like war films watch Hurt Locker and Enemy at the Gates.
Great Escape remastered in HD!
Source Code is a good one, I watched that the other day, not everyone's cup of tea though..
