For the most part, these movies do tend to take themselves too seriously, even when they go for the laughs. So I’d agree. Except.
The TV batman was kinda campy, and I liked it. Likewise the first Iron Man. Most of the Batmans are too convoluted to enjoy. Plus the stupid things are so dark (meaning filmed in the dark) and noisy.
I hated The Lone Ranger when I saw it first, expecting it to be something like what I grew up with. But the second time I saw it, I saw it did not intend to take itself seriously (Depp’s Tonto: “Did my name come up?) Really enjoyed it.
