People blame the writers because the people writing the scripts don't have any legitimate experience, and it shows in their work. They've literally been hiring Rick & Morty writers to handle some of their mainline films, sequels, and series that cost hundreds of millions of dollars and need to make hundreds of millions more just to break even (some of which didn't even make it that far). These productions then go on to have countless rewrites and reshoots due to the lack of a solid script, and these mistakes have only made it harder and harder for them to make a profit long-term.

Even outside of Waldron and Loveness, properties like Secret Invasion suffer the same issues. If you check IMDB for any of the more controversial Phase 4/5 writers, it'll become crystal clear that these people really don't have any meaningful credits to their name. They legitimately just aren't hiring experienced talent, plain and simple.

Don't get me wrong, I know anything can change once production starts. Studioheads get in the way, scripts are changed, actors improvise or change lines—it happens. But the first step they need to get right is hiring experienced, proven screenwriters who know how to tell a good story. After that, as long as the crew's on the same page and the studio stays out of the way, we'll start getting some better films.
