Moore has some fine moments in this one---the best is in the centrifuge, IMO. I also like the fight with Chang in Venice, the PTS (until Jaws flaps his wings 
), the suspense in the Venice lab, the sequence with Drax's dogs chasing down the girl in the woods, the hunting bit ("Such good sport")...and I actually didn't mind Bond going into space, actually---I always thought that the best way to end Blofeld (in #25? LOL) would be having Bond chase him across the surface of the moon in EVA suits, just when ESB had thought he'd got away from it all 
But there is so much in MR that disturbs my sensibilities that it inevitably lands in my lowers (currently #22 of 24, behind NSNA and DAD, until SP officially pushes it down to #23): Jaws trying to 'fly'...the Bondola/double-taking pigeon...the guy on the gurney in the cigarette billboard...the really fake snake (Ed Wood would be proud)...the space station rotation magically providing gravity by magic instead of any actually centrifugal design...Jaws' love affair and toast, etc., et al. It's all fun, certainly, but at some point it crosses that fuzzy line for me to the point where cringes outweigh happy grins.
Cheers to all who love it, of course 
It's certainly preferable to a couple of other Moore entries 
...and it made loads of cash. So what do I know?
