I just watched Merantau, and it was awesome. Of course, it wasn't as great as the Raid: Redemption, but it still rocked. I can see why so many people compare it to Ong Bak and the Protector, even though Iko Uwais uses silat in this movie, which is noticeably different than muay Thai. Still, it's a martial arts movie about a guy who lives in a small, extremely rural Asian village and goes to a large city where he confronts a criminal organization and kicks everybody's ass. It also features many bad guys writhing on the ground after getting beaten. And the main character gets picked up by the neck and choked out in the final fight, eyes bulging from blood pressure, and manages to get out of it, just like in Ong Bak. Also, it features a fight scene with a long, continuous shot, which is something for which the protector is famous (:P). It wasn't nearly as long as the scene in the Protector, though. The only problem I had was that it started off a bit slow and it didn't have quite as much action as I had hoped. It still had a good amount, though, and the fights were awesome and VERY well shot.
I really hope Iko Uwais will be in a whole lot more action movies and have a good long career. I'm probably going to buy this movie some time. I heard that they're making a sequel to the Raid: Redemption. I hope it doesn't take too long to reach the west.
