I would rate it slightly higher as "good," but not "great." And I'm not disagreeing with you, but in response to your point about his portrayal, how much of what you didn't like was his actual acting vs. how the character was written? Again, I'm not disagreeing with you, but just asking the question. It just seemed to me that the story that was written didn't really allow a lot of room for Batman to not feel a bit shallow no matter who was playing him. But I could be wrong.
Unfortunately with Affleck, he's one of those actors that very rarely seems to be able to be fully immerse me in a role that I forget it is the actor. He has in a couple of films, but his Batman/Bruce Wayne...it never felt like I forgot he was Ben Affleck. It could be just the scripts, obviously, and the lack of character development for sure.
And a follow-up question: How much of your reaction is just a visceral reaction because it wasn't Bale's/Nolan's Batman? As enamored as you are with that on-screen portrayal of Batman (and right so--I am as well), is it possible that that is influencing your feelings, even if only a little bit? Maybe for you, it isn't an issue. But I will fully admit that those films have me inherently biased against anyone else trying to portray that character.
Fair question. You know me better than anyone on here, and know I'm as hardcore a Bat-fan and collector as they come, including me absolutely being a Dark Knight Trilogy fanboy. But I was just as fond of Keaton's portrayal of the character back in the day. So I'd say it may have had a little bit of influence in how I felt when it was announced, but by the time I saw both Affleck films, it was at home, and enough time had passed where i just was looking to enjoy it. And he just didn't deliver for me. It never felt right. Bale is my favorite, for sure, but even he wasn't perfect. But its all in the test of "do I forget the actor when I see the movie and just watch the character?" For Keaton, that answer was yes. For Bale, that was yes. For Kilmer...it was spotty. For Clooney it was an absolute no. And Affleck - no. (Not counting Adam West, or animated Batman that is voiced by Conroy - who incidentally has the best Bat-voice.) I think he (Affleck) probably would have been better than Clooney in his own solo Bat-movie, but still, no. It was just "oh there's Affleck playing Batman," as opposed to "That's Batman." It's a feel thing. And that has been a problem with Affleck for me, for his entire career.
I totally understand why people dig him as Batman, and I obviously know there are people who despised the Nolan trilogy and Bale as Batman. Totally get it, and that's fine. Affleck wasn't for me. Rumors circulating about Kit Harrington as Batman. Not sure about that. Then again, I wasn't sold on Heath Ledger as the Joker until I saw it. And that was incredible. So who knows.
p.s. it also didn't help that the movies themselves (Bat v. Supes, Justice League) both sucked, IMO. I am very disappointed in DC/Warners. I thought they got Wonder Woman down pretty well, and have hopes for Aquaman, but I am in general very disappointed with Warners in the post-Dark Knight Trilogy era. They had a chance to fashion a more realistic way of presenting superheros, and instead they just got greedy and tried to be Marvel. I'm very glad the Dark Knight Trilogy is considered a full-on standalone. It's a shining pillar in a sea of mediocrity.
