Good concept but stopped functioning – Watchlist - Movie To-Do List Review

I like the idea of this app. So many times I’m standing in front of the DVD rentals thinking, “What was it that I wanted to see?” This keeps track of those nicely. But now for some reason, it won’t let me mark them off when I’ve seen them. If it’s a “to-do” list, I should be able to cross them off when I’m done. Maybe it’s time for an update?
