I have a soft spot for Batman Forever.
Me too. Mostly because of nostalgia. It's one of the first movies I can remember being really excited for and mostly satisfied with (keep in mind I was about 12 at the time of its release). Coming off
"Ace Ventura: Pet Detective",
"The Mask", and
"Dumb and Dumber", I was big fan of Jim Carrey. I also loved The Riddler, because of growing up watching Frank Gorshin in the role on
"Batman" and John Glover in
"Batman: The Animated Series". His performance was a decent tribute to Gorshin.
To this day, I still like Kilmer better than Keaton as Batman and Bruce Wayne, and I also thought Chris O'Donnell was an okay Robin (despite the horrible costume). Nicole Kidman was delectable, but I couldn't have predicted she'd become a great actress based on her work in this. I really hated that scene where Batman comes to Chase's bedroom in costume, though. That's probably the worst part to me. Did he expect to get in bed with her like that?

Equally absurd is him being in court in the batsuit! I liked his smile when Chase confessed to being in love with Bruce Wayne, even if it's weird to see Batman smile so broadly.
Despite all the lame camp, there were some effective relatively serious moments. For example, there's a great scene in the Batcave where Wayne and Grayson are arguing over Grayson's insistence on becoming his partner to get revenge on Two-Face. It has a rather unintentionally funny serious line where Kilmer very unconvincingly says,
"I can stop you", but otherwise works dramatically. Wayne also has some flashbacks to his parents' funeral which are well-acted. Those and the Robin arc give the movie the tiniest bit of dramatic weight.
The movie's portrayal of the Two-Face character is, of course, revolting, but as a kid I didn't mind. I could at least enjoy the movie on a superficial level for the fun set design (Two-Face's room that's split down the middle with a different girlfriend for each side is kind of endearing in its ridiculousness) and The Riddler's crazy island with "holey rusted metal" is sorta neat. It's a profoundly dumb movie, but it is not without its shallow charms.
It means more to me than the 1989 Batman, because while it doesn't have a standout performance like Nicholson's, it has more memorable scenes and a tone that was much more palatable to me as a child. I have no nostalgia for the original Batman, not only because I didn't see it when it was first released, but also because I didn't find it terribly impressive as either drama or camp.
"Batman Forever" at least had camp value and a few attempts at seriously exploring Bruce Wayne's past and Dick Grayson's tragedy that I can respect.
