It's a fun game, worth playing and will be a lot of fun when entertaining guests.
Questions are based on a wide variety of movies so you will run into questions that you've no idea about, and questions that you will answer instantly. The avatar animations are great too!
I find the marketing hype about the “Big Button Controller” a little annoying, but they really are great and easy to use. Especially as they are wireless! A shame that they require the IR receiver it comes with and that they can't use the xbox's built in IR or the same wireless technology that the game controllers use, but that's not a big deal.
My only after-purchase thoughts are that you could almost get away with just hiring this game as needed. But I am glad I bought it as we play it quite a bit.
