Up until recently I was relying on something called Trakt but it has become increasingly unreliable or erratic - it just seems to randomly rearrange the order of its older movie releases now

What are the best alternative new releases sites please?
watchsomuch.to has been pretty good for me. You may also want to sort by language, since tons of foreign films tend to get listed too.
