They still make fun of bad movies, though. But they also get plenty of blockbuster requests. Anyway, the full RT on Avengers is pretty decent, a lot of jokes making fun of Hawkeye's "usefulness" as part of the team. Other riffs they've done on good movies have been good, the riffing concept doesn't always have to be for bad movies.
Full "sample" here: LINK
I wouldn't say it's one of their best blockbuster efforts, or even the best of the MCU movies they've riffed on, but it's still pretty fun to watch movies with these guys.
$4 is worth it for that.
