The criticism of the movie can be great, that is basically what the whole riff is, but in this case it is not humerous complaining it is just moaning. And I have listened to that many times while watching the movie with my friends. I have watched a good deal of MST3K and even if the jokes get sparse at times (which really isn't that common, at least not the the degree they do halfway through EP.1) they still keep them coming. On the TPM riff I really got the impression that they were hating having to do the riff.
