I watched most of the horrors at Screamfest and I saw this with my BFFs. I was impressed with the look of Needle...visually its pretty much perfect...definitely not a film for the hardcore gorehounds, as there isn't much blood, instead there are some good scares with some cool spfx...two of the kills were impressive.
I really enjoyed this film for two main reasons, firstly it uses a new killing device/machine which i've never seen in a horror film before and secondly because of the great acting. I have seen Travis Fimmel in the Beast and he's way better in Needle...the other actors are great too.
My ratings are as follows;
Story - 8/10 Acting - 8/10 Visual - 9/10 Efx - 7/10 Score - 7/10 Blood & gore - 6/10
I guess overall I'd give it an 8.
Definitely worth seeing, I can't wait for the DVD!
