If you're in the mood for watching a movie but can't decide what to watch, give Movielator a try. The Windows Phone app was recently released to the Store and will randomly pull up movie titles as suggestions on what to watch. The results are based on genre or you can just randomly generate recommendations across the board from all genres.
Movielator will generate a selection of twelve movie titles that you can read a short synopsis of to help you narrow down your search. The app reminds me of those food apps that generate random recipes or resturaunts when you just can't decide what you're in the mood for.
