If a movie is 6 and up on imbd, I'll generally watch it thinking the movie will at least be okay. 5 and below, if I watch it, I'll be thinking the movie has flaws.TBH I think IMDB is the worst way to decide whether to watch a movie (the old pre-voting BS that used to go on before they banned it shows that lots of users vote on things other than the quality of the movie itself). I had to look at the cast list to see whether I'd seen Ava, and can confirm I did and I liked it. Wasn't great, but a decent entry in the women do Taken bunch of movies out there. I too like Chastain which is odd because I'm not a fan of red heads normally.
"Ava" is far above a 5.1 out of 10 movie. Probably, the best movie I've seen so far this year.
