No, they don't generate drama or do stupid things online. But they've been doing these shows for 10 years now, it's hard to keep quality up that long.
I don't think they're really falling off, it's just that sometimes an episode isn't as funny as others. It's the same for other things like MST3K too, sometimes an episode is just OK instead of an instant classic. This is literally just 3-4 friends watching random movies without a guarantee of fun or having something funny to say.
I do think the small gimmicks help the episodes more than doing random WotW crapshoots, though. The Christmas episodes are some of my favorites, maybe that's helped by how rarely they happen, but it also provides a structure and a theme to riff on. They should bring back the Battle of the Genres, judging which video is the best representation of its purported genre, and things like that.
