I really like the concept here, but it shows a very limited amount of info about each movie. Maybe if I could click on the card to expand more details (maybe sourced from imdb or something) this would be a lot more helpful.

Also, does this take into account previous decisions to show movies that are more like the ones that I've already liked?

Nicely done! I made something similar a few years back for quickly rating movies you've seen and marking ones you haven't seen but want to. I never did much with it, but it's still fun to play with every once in awhile even being years out of date. Yours looks much nicer though :)
