Is there a website that names the newest and best movies?

well theres a website you could go to that has almost all the movies that came out – plus the movies in theaters still.

I have The Internet Movie Database website bookmarked. They have info on past, present and coming soon movies, not just the best, but includes god and bad as well.. . . In theaters, DVD and Blu-Ray.

Rottentomatoes.com is the best site I know for this purpose.

AllMovie is pretty good too.

Rotten Tomatoes is a good site but the best movie will depend on who you ask. I mean they have given bad reviews on movies I thought were good.

I would pick a few reviewers/sites to follow. You will pretty quickly find which sites you like the best. As well as all those linked above, I would try:
http://www.ew.com/ew/movies
http://movies.nytimes.com/pages/movies/index.html
http://www.newyorker.com/topics/movies
http://www.rollingstone.com/reviews/movie

Roger Ebert writes my favorite site. He has been very ill but he still keeps churning out the reviews. It’s the first place I look to see if a film might be worthwhile.

A Critical Consensus uses a large number of film critics, and averages their ratings of movies.
