My favorite is when they they say something like "it starts getting good in season 3". Like I'm going to watch tens of hours of a show that kind of sucks just to see if it actually starts getting good or not?

Of course, the reality is that they aren't really watching the show like I would - as in, they aren't sitting down and giving it their undivided attention. The show is on, but they're also on their phones the entire time, or it's on in the background and they are doing something else, or whatever. Probably one of the reasons why the show feels like it's full of filler - they need to make sure that someone that's only sort of paying attention can still follow what's going on.
