i disagree about the 1st and the 4th story...
i just watched phobia and although I agree this aint anything new, I would still say its nicely done and not at all worn out.
the 3rd had its funny moments(when he spoiled Shutter I laughed so hard...), the 2nd was just lame and the FX pretty bad. But the 1st one and the last one really stand out. One room, no dialogue, one actress setting I found pretty well done. The fourth was just plainly scary and I totally disagree with the comment writer before, although it was obvious what was gonna happen it was still scary (i`ve seen a lot of horror flicks, dont start that...). If u like thai horror just watch it, but make sure u get to see Shutter first (the Thai version not the crap-made US version, as always...)
8/10 from me.
