No mention of the resi series... ?

Granted the first and second are more action than horror films but the last one, resident evil extermination (or it might be extreme something beginning with e...) is similar to the type of films you mention in the op, apoclyptic ones, and is a decent bit better than the first 2 imo....

28 weeks later was amazing in my opinion, i didn't know there where alot of people who didn't like it... as far as i am concerned its one of the best horror/apoclyptic type films ive seen, i saw 28 days after seeing 28 weeks which probably made 28 weeks alot better for me....

Seen the ring's... watched the first one in the cinema and its the only time i have been peaking through the cracks in my fingers at the sreen... went a bit downhill after the first one.... The grudge was also a pretty good watch... quite similar to the ring...
