10/10 on the entertainment level.
Sure the acting was spotty at some parts and the effects sucked at times but the story was so great that didn't even bother me once.
To compare to other movies I've seen taking all things into consideration I would probably give it about an 8.5 out of 10.
Simply put I was completely and totally entertained by this movie. It's just an awesome movie to watch. What more can you ask for when you put on a movie?
Anything with Tarantino attached seems to be a winner in my book.
