This was a pretty good effort at one shot. It was funny in parts. It was conceptually good. Perhaps they could have ended it better by after having admitted all these stupid things to each other the world doesn't actually end at all. But there was some nice comedy in it. For a one shot film it was a pretty good effort. They could have lifted the performances just a little perhaps.
There was some decent comedy here, but a lot of waiting around for something to happen. The end of the world maybe wasn't the best choice for you guys to combine with the one shot thing.
The inside location did nothing for me, but once the shot got outside it was much better.
