Imagine absolutely loving the original Bill and Ted movies where the entire purpose was rooting for the two underdogs that were endlessly goofy and wholesome to save the world. Now, Imagine a cynical, pandering cash grab in 2020 that tells you that these two were in fact lovers, and only their boring, painfully untalented, and ridiculous caricatures of daughters as well as completely unnecessary team of unrelated characters with absolutely nothing relevant to do or interesting to say(except for Death, funnily enough) do the job Bill and Ted aren't allowed to do because it's 2020. Now, shove Kid Cudi into the movie to barely get through "I'm actually a genius when it comes to physics isn't that funny because I'm Kid Cudi" lines with a few glimpses of the spirit of the originals in certain scenes. That should give you an idea of the nostalgia vampirism that this movie is attempting. Any time anyone other than Bill and Ted ( and in the last 20 minutes William Sadler as Death) are on the screen, it's unfunny, boring padding to frame the daughters as being able to do what Bill and Ted can't because, again, it's 2020. It's a few funny gags with over an hour of the stiff, unfunny daughters imitating an imitation of an imitation, and gathering together a group of entirely unrelated musicians that do nothing other than represent required racial demographics and try to make you think about the first movie. Problem is, it just makes you realize how great the originals are, and how that magic was used to convince you to spend $20 on nostalgia.
I've left out more details for the sake of spoilers, but do yourself a favor and don't support more destruction of things you loved. However, if you want to watch a largely unfunny, boring, tone deaf, and annoying corporate hack job that turns Bill and Ted into to incompetent losers the originals were trying to show you WASNT TRUE...then waste your $20.
