Part of the problem with stories like this where they fundamentally change the character is that they last for up to a year or more. Truth started in, what, June? July? of last year. So we're already up to half a year with an underpowered Superman who runs around in a T-shirt and jeans. A gimmick that Morrison did way better for a much shorter time. I guess I just don't like the idea of an underpowered Superman. It just comes off as lazy writing. They can't come up with anything else so it's "Oh, let's strip him of his powers...again!"
Right now I think that's the biggest problem with the books is that you get these year long story arcs. There's no jumping on point for new readers.
