I use Criticker to get recommendations and that's pretty much I need when it comes to social movie services. Also, one thing I dislike about Criticker - or IMDB or that matter - is how the lock-in my data, which basically means that I have to re-start the process of telling which movies I like and dislike each time I find a new service. Incredibly annoying and quite rude. What is Sharemovi.es policy on this?
