Cool. Thanks.
They got rid of the underwear-on-the-outside. Now he's just a man in blue pants who punches things.
Men can wear blue pants and punch things.
I get that it's a sort of whimsical fantastical type setting of the sort that has traditionally appealed to children, but I think by this point in history, we've seen more than enough R-rated movies and comic books designed to appeal to an adult audience that we know that superhero stories do not necessarily have to be children's stories. Besides which, even when I was a child, I preferred stories about adults. You don't have to be an adult to appreciate stories about adults, just as you don't have to be a child to appreciate stories about children (I just tend not to like stories about children).
I guess since it's just one issue, I can ride it out and see what they do with Reborn. I've made no secret that I don't like the Jon element to things, but if it just gets to the point where he's a character in his own book that I can ignore and a minor character in Superman and Action Comics who mostly is in the background and dealt with through the prism of two adults raising children, that might be mildly palatable.
Just as an aside, I have to mention that my favorite Superman, the New52 Superman, wore blue jeans when he was starting out and eventually body armor, possible Superman's least silly costumes ever.
But there's nothing wrong with blue pants. I mean, come on. They got rid of the trunks (A move I agreed with). What more do we want? Superman to fly off and fight crime in a business suit? Blue pants are fine. Even the trunks weren't horrific given their history (They were common in strongmen competitions and such and conveyed something to readers in 1938 back when that stuff was still popular, or at least in the cultural memory), but I'm glad they got rid of them.
The only caveat to the trunks thing is that I think if they were ever to do an R-Rated Man Men style Superman title set in the 1950s (An idea that I've been pushing for a while), I would put Superman back in trunks in that title only, just because it'd fit the time period, and the whole idea would be to mesh all the old tropes (changing in a phone booth, etc, the old sayings, etc.) with the smokey rooms, alcohol, and womanizing of a 50s newsroom depicted frankly with an adult audience in mind ala Mad Men, the television show set in the 50s devoted to a Madison Avenue advertising firm.
