THE AMAZING MAURICE has decent-to-good critic and audience ratings, in fact. Which seems to be the problem; the general consensus seems to be that the movie’s… all right. No need to rush out and see it, but it’s not a waste of money. You won’t throw things at the screen at what they did to Pratchett’s story.
It’s not quite ‘damning with faint praise,’ though. ‘A stretch in Purgatory to head off possible concerns raised in the last evaluation report,’ maybe? Although admittedly that doesn’t even remotely scan.
