Well, maybe you're the one out of the loop since they've been doing this for many movies. I don't see why she has to have been in "crappy movie/tv show", so that's irrelevant. And the rest is just... yeah.
If you don't like to read the description, don't read it. They usually add it at the end, based on what I've seen, so once you get to it, skip it. Either way, not everyone is in the 'loop'. So by just posting news like 'so and so in such movie' wouldn't really satisfy the reader.
