The Conjuring was the best one of recent times for me. The 2nd part wasn’t great but I enjoyed the 1st one.
Also The Ritual was great for about ¾ and then went off the rails and fizzled out with a terrible ending, which seems to be a problem with most modern horrors, they just can’t seem to stick the landing.
Event Horizon is a classic, shat myself watching that back in the day. Same with Salem’s Lot. Creep, the one about the lass stuck in the London underground overnight was pretty good iirc.
