I wonder if it's because there didn't seem to be an awful lot of new ground for them to cover? If I'm remembering this properly, when it was announced, they stated that one thing they were going to discuss was Morrissey's Latino fans... as we all know this has been done before.... what's to learn? No offense to any fans that may have been involved with filming, etc, but what I mean is that it struck me as a bit lazy of the production team to go over something that has been covered for the past what, 10 years?!
It's a shame in a sense that the documentary won't be made, but I'd rather that it wasn't made if it's just a re-hash of stuff that's already out there. They could have followed him to Italy and done the special on the recording of ROTT, and discussed the influence that Italy had on him, and so forth...
