I usually do the setup, then play a mock game by myself as I read through the rules and if the rules are very unclear I will watch a how to video. I find I have a more thorough understanding of the game doing it this way rather than by reading straight through the rules first. I frequently teach games so, getting this sort of understanding, though more time consuming now, means less looking at the rules while teaching and a smoother experience for everyone.
I’m skeptical of all game and movie adaptations. The fact is, the IP owner almost always a megacorp that specializes in taking as much as possible while giving as little as possible in return. I know that the games are frequently made by known board game designers, but ultimate power over the projects is held by the IP owner and they aren’t interested in a good game, only a profitable one.
