How I felt about it. At one point, Jim Carrey takes a momentary break from his effeminate Holloween-costumed routine and asks: "Was that over the top? I can never tell." The audience has little problem, however. The silliness of it all is ceaseless, and only slightly more subtle than the blatant ridiculousness of the 1960s camp television version of Batman.
Which is probably how it should be. Both the heroes and villains have no intention of investing their pieces of eight in a bank CD. Instead, they blow it on high-tech toys and lavish interior decorating, which in film-speak translates to props and set design.
It's not enough for Two Face or The Riddler to rule Gotham. They have to do it in style, and the same is true for vigilantes Batman and Robin. They may not get to make outrageous faces, or laugh like a lunatic receiving a sexual favor, but they still get to dress up like the punisher in a game of S&M.
They get some good lines as well, spoken with deadpan earnesty. "I'll get drive-thru," oblivious of the incongruity of a multi-million dollar car idling at a fast-food delivery window. "The Batsignal is not a beeper." Or, I don't care how hot-looking you are, if you want to be rescued, get in trouble first.
Of course it's over the top. The laws of physics are taken from Road Runner cartoons. Batman fires a hook at a marble wall, with enough force for it to pass through the wall, yet not causing enough damage to the wall to prevent the hook from falling back out, even when this same hook is used to stop the plunge of a multi-ton metal sphere. Never mind that anyone inside the sphere would continue travelling at ninety miles per hour. When Kidman is free-falling to her presumed death, Batman saves her with a rope tied around her waist, yet when the rope breaks her fall, it fails to rip her in two or even damage her internal organs.
I could go on, but Batman Forever is not meant to be taken seriously. It is a fabulously expensive, but well cast, live action cartoon that provides passable-plus escapist entertainment.
