Finally, a remake worth watching.
Just watched this for the first time and I was pleasantly surprised. I was expecting a watered-down remake of an 80s classic (as so many of them are) and this was a worthy successor to the original. From the synth score, Taxi Driver-style sequences of cruising around rotten neighbourhoods, the bleak hopelessness of the main character, the director clearly gets Grindhouse.
I've practically given up on horror in the 2000s (not counting the real extreme stuff such as A Serbian Film etc), which is a sea of bland found footage, insipid remakes, countless zombies and dull ghosts, but this is a rare gem. It really does recapture the vibe of the likes of the original Maniac and Nightmares in a Damaged Brain, and the POV shots of someone losing their mind are extremely effective and unsettling.
Highly recommended.
