Weddings these days go too far. We've taken something which should be fairly simple and formulaic (2 kosher witnesses + kesubah under chuppah, yichud, then seudah + sheva brachos) and added all these halakhically unnecessary things like dancing and entertainment and huge parties in what feels more like a show of one-upmanship rather than a mitzvah. Plus it's ahistoric: you cannot convince me that my shtetl-dwelling ancestors did all this, no one could have afforded it back then. It all makes me dread my eventual wedding (B''EH)—as much as I want to fulfill the associated mitzvos, the ceremony and such is just going to be a huge headache.
A lot of this could also apply to bar mitzvah celebrations in some communities, but that's another hot take.
