I remember watching the first one last year. And i for one was quite impressed with results. I do agree the movie is actually too violent for kids but otherwise i felt this was an solid effort by Fulci. Some likeable characters, good acting and a few nice action set pieces. Nothing groundbreaking but there are worse ways to spend 90 minutes IMO.
I still have to watch the sequel (own the German double bill DVD) but if it's anything like the first one then i'm sure i'll have a good time.
