What I would also really like is the ability to write a review without the hassle.

I would really love it if we could finally write reviews directly within the Movie Base app, without having to sign up somewhere else to do so. I understand the need to keep an eye on reviews, but that doesn't really work on Trakt either—if you look at certain movies, the discussions there are often about politics rather than the films themselves. So, I think Movie Base could handle it the same way.
