Well, to be fair it was well acted, the music was great and I very much liked the comedy aspect in it. It was also nice to see people actually fighting back, for once, and NOT behaving like a dumb bunch of helpless chicken.

Other than that, the plot had many, many holes and the final twist actually ruined the whole story for me. It was also very inconsistent about which "laws" these shadows had to follow - sometimes they were doing the same things as the people on the upside, but other times not... however it fit the plot in that moment, it seems. 'Us' tries very hard to be deep and stuff, but it really is not.

However, while it is not as great as I had wished it to be, it also not the worst horror movie I have ever seen. So, for a horror movie night it's OK to watch but don't expect too much, I guess.
