I have seen a lot of Batman media...probably more than I should have, haha. I've seen pretty much all of the 90s stuff, all of the cartoons except for Beware the Batman, and a lot of the animated films, too. Of everything I've seen, I think I liked Batman: Mask of the Phantasm, Batman Beyond (including the movie, at least once I saw the original version) and the first two seasons of The Batman the most. Gotham was very much a mixed bag in that it has the best portrayal of some of the villains I've ever seen - Penguin and The Riddler especially - but it severely led down by its terrible final season and absolutely awful portrayal of the Joker, which stings more than it should because they were getting things right with Jerome as it was.
I actually kinda liked Batman vs. Teenage Mutant Ninja Turtles as well for some reason
Oh, also the LEGO Batman movie. That was just hilarious. It was 60s Batman modernised for current generation kids, with some amazing easter eggs for older fans. It also started with a fantastic musical number.
About all I didn't enjoy in some form were Nolan's films. I will never understand why people glorify Nolan's trilogy so much - it's very much like the MCU in that it doesn't really capture the spirit of the characters or the comics. Even the cheesy 90s movies did a better job, because one of Batman's defining character traits is that he's a detective, and there...isn't really much of that in Nolan's trilogy. Nolan's Batman is a capable inventor, but otherwise he's a mindless brawler - he's not a detective, or a scientist, or even a strategic thinker. There's a lack of intelligence in Nolan's Batman that really doesn't sit right with me. I feel like much of the hype surrounding Nolan's trilogy comes from how the 90s Batman movies often followed more in the spirit of the 60s TV show and the Dick Sprang comics (which gave us things like
this) rather than the darker side of Batman, which up to that point hadn't really been shown outside of the TV series. The gritty realism is nice, but it comes at the expense of too much else in my opinion.
Oh, and there was The Killing Joke, too. That is one of the worst comic book adaptations I have ever seen - bringing in Mark Hamill for the Joker's voice isn't going to hide the fact that they pad it out with pointless nonsense (including Batman and Batgirl making out on the roof for some reason?!) for about an hour longer than they should and it completely misses the point of WHY that comic is considered so iconic. Even Batman Ninja was better, and that film was...so bad it was good, hahaha.
I'm still waiting for someone get the Joker right in live action, too. Honestly I've not seen live action media try and fail to get comics right this badly outside of the Dark Phoenix Saga in X-Men...which they really, REALLY need to leave alone. Whilst the Joker is Batman's most iconic villain, if they can't get the presentation right - which they definitely can't - they really need to leave him alone and focus on someone else. One of Batman's biggest draws is his ridiculously huge gallery of colourful and interesting villains so it's not like they're stuck for choice.
I don't have any particularly strong feelings for or against Robert Pattison playing Batman. I hold out very little hope his movie will be any good simply because DC are failing hard with their live action movies and I doubt this will be any different.
