All those stills look really good. The animation style is a lot better than that single image made it out to be. I'd like to see it in motion to really make a judgment. I do see some of Manpul's influence in the animation as well.
I wonder if that guy Clark is bringing coffee to is Jimmy? They were more contemporaries in American Alien. I hope they do show some of the first issue in flashback, that was a really solid take and that version of the Kents and the interpretation of Smallville as all kinda in on the secret really worked for me.
I'm kind of surprised that they are really doing such a direct adaptation of American Alien. I expected it to pull some elements from it, but enough that they could kinda hand wave any connection away. But the googled proto-Superman kinda dispels any idea at deniability. Man, I wonder if they are going to have a special edition with a copy of the American Alien trade redressed to just name the artists, haha. They like the story but just want to memoryhole Landis' connection completely.
