I liked it a lot as a kid. I watched it again a few days ago, and it really went down in my eyes. That being said, I really liked Val Kilmer and I loved the scenes with Bruce Wayne. I especially loved the overall theme of the film of Bruce giving up his alternate identity and I even love the name "Batman Forever". But once he put on the Bat-Nipples and drove to Neon Gotham, it took a nose dive. To sum it up, the scenes that were primarily dialog and were handled half-seriously were good, but the ones that actually involved any action came off way incredibly cheesy. I actually thought the Batmobile riding up the wall was standard when I was a kid, and even when I'm older I don't mind it as much as the cheesy score they play during the scene that makes it way more lame then it needs to be.
I never realized how 1960s Riddler and Two Face seemed. The scenes where they're playing "battleship" and pretending to be trick-or-treaters just scream that. I also found it ridiculous how they completely missed the mark with the Two Face. With Joker, it kind of made sense to have him be involved with the making of Batman to have the final conflict be more personal. But Harvey and Bruce are friends, he didn't need the circus scene to have the final battle seem bigger. And he also didn't need to have a connection to Robin and not Batman, since he was already being set up too much as Riddler's sidekick. I also never realized how useless and annoying Chris O'Donnell's Robin was. Talk about adding truth to the title "Boy Hostage." I really can't stand how old he looks, he really needed to be at an age where he would actually looked like he needed a parent. And O'Donnell as an actor didn't add much either.
For some reason, I also thought the designs on the Sonar Suit and Batmobile were awesome as a kid too. To me, it just felt normal and Batman-like. I actually didn't even notice the switch in directors either until I was older. And that wasn't until after I watched Batman and Robin and thought to myself "Shouldn't be Batman be kinda darker?" In retrospect, I was a stupid kid. Overall, it was an okay movie but it ages worse and worse and it marks an ugly footnote in the Batman movie history. But its still the best Shumacher film. Overall, a 6/10.
