I read about this in Fangoria a while back and it peaked my interest. I saw the commercial for it on TV last week and made sure I got to see it this weekend.
I really did like it. Hubby wasn't too happy about the subtitling, but it didn't bother me any. I won't give anything away, but some of the creatures and other FX (digital and makeup) were pretty cool! I only wish there was more of the labyrinth itself.
This flick is rated R. Don't let the title fool you, it's definitely not for kids. Quite graphic. (IMHO, it's about time that more genre films get back to an R rating. I'm tired of PG:13 horror films. )
Anyhow, long story short, I recommend it.
