Glow in the dark vehicles… of course. Batman travels at night… by stealth, and should use a car that can be seen a mile away. Robin. Uh-huh. Well, at least Alfred didn’t change too much. Carrey looked as if he had a great time filming and overshadowed a Tommy Lee Jones who just didn’t seem all too comfortable at times. Val Kilmer didn’t play too bad a Batman, but didn’t last long enough to do better.
Schumacher was, at the time, a rather good director, but did little to advance the franchise except for bringing his own personal vision to light (and delivered a dumbed down family fun version as Warner’s had ordered)… and not at all what anyone else who paid to see the movie had wanted. The writing was on the wall.
Bring popcorn, and plan a bathroom break.
