They can't all be winners.
I mean, yeah it was action packed and the fight over the parachute was really cool. And Bond did have space elements in the movies before... but Moonraker kind of felt like it was jumping the shark a bit here.
Thankfully it recovered, but this was a little too much for a 007 movie. And that is saying something because, when you go see a 007 movie you expect it to be a little too much from the start.
