Do not play a continuity drinking game you will die
In all seriousness everyone is stupid, unscary, and there is no exposition to aid in the terrible unfollowable story
The aliens are terrible at their jobs, allowing a random seamstress to kill them by not using telekinesis which they have or just using a ray from their overpowered and inconsistent spaceship and making tropey sneaking movements and extending toes I laughed more than was afraid and was perplexed even more than both combined
Overall this movie is a masterclass of everything you could possibly do wrong and every mistake you could make. 0/10000 watch anything else, even the watchers is better, and the Big Bang theory somehow scarier.
