Watching a movie shouldnt feel like work.. hello!! Let me relax !.. I have to make enough choices in my real life... this move DIY experience sucks, I got to I guess a third of the movie, and got tired. I really couldn't continue. One choice after another, then you can also go back and change it all, you never know how much of a movie you got left... I'm guessing it could last about 4 hours if you keep changing your choices. It's a really interesting concept at first but it doesn't work.. Maybe in cartoons I see the point , but for grown ups , it gets really enoying and frustrating.. waste of time... will not watch something like this again.
