Obviously, remorselessly slaying henchmen is entertaining and fun. So much fun it even makes Batman himself smile.
Also fun:
- Imagery catering to the goth kid crowd. Lots of wild, frizzy hair, stark black and white color schemes, and horror music complete with choir. A shame Johnny Depp and Helena Bonham-Carter were too young to be thrown in there too. Add those two and a little claymation and Burton could've called Returns his opus and retired satisfied.
- Loading your plane with machine guns, missiles, and an elaborate targeting system, having a clear run at a target that's standing still, and missing every single shot. Said jet can be brought down by one bullet. (Oh, I get it. By “fun”, you mean “absurd like a Bugs Bunny cartoon”)
- Danny DeVito being raised in the sewer by both intelligent penguins AND a circus, biting people's noses off, and bleeding to death out the mouth. (Please note that flipper-handed mutants bleed
black.)
- Penguin's henchmen? Clowns. Joker's henchmen? Guys in black leather.
- Revealing your secret identity every single time you have a second date with a random broad who you will probably never see again. Bruce Wayne: Hopeless Romantic
- Lando Dent, District Attorney of Cloud City.
- Glorified cameos from a fat and largely useless Commissioner Gordon.
- Renowned photographers not knowing what the richest and most famous man in town looks like.
And some fun facts:
- In groups, cats have the power to resurrect the dead (and give them eight 1-Ups) by chewing on them.
- Bruce Wayne sleeps upside-down!
- Batman's first supervillain turned out to be the guy who killed his parents! Isn't that convenient?
- The Joker is roughly in his 50's. You can tell this not just from his wrinkles and bloated features, but by the fact he wears the waist of his pants pulled all the way up above his belly button.
- If ugly matte paintings are to be believed, Gotham is not only the most cramped and tightly packed city ever built, it's composed mostly of brown churches and construction sites located 10 stories up. (again, probably because of the crampedness. They have to build the new buildings on top of the old ones!)
