What the heck is going on in this thread? I though MST3K, and by extension Rifftrax, was one of the ultimate sacred cows of nerdom. Where is all this hate popping up from?
Rifftrax dares to make fun of "good" movies? They dare to seek profit on their time and work by charging $4? I'll admit the sample(s) of the Avengers Riff aren't great but the samples are rarely indicative of the best jokes, unlike trailers to movies they don't spoil the best in the previews. The whole thing is hardly their best work either but there is some good, humorous, stuff in it. It's just fun to watch movies with these guys. (Though the VODs are much, much funnier (also tend to be much more expensive.)
The Avengers Riff is a decent one, though. But hardly as hard -hitting as their Riffs on, say, the Twilight movies. It is "hard" to riff on a good movie.
