Like so much of Liefeld's work, this is simultaneously terrible, amazing, stupid, and brilliant.
It breaks from standard convention of comics in a way that all his other crap never managed to. (Whether it goes too far in the other direction, well, overcompensation happens.) It's so... HIM... in a lot of the ways that are amusing about Liefeld, and actually relatively few of the ways that aren't. If you wanted to pick a comic to show someone something that truly encapsulates Rob Liefeld without instantly making them hate him, this would be the comic to do it with.
Honestly? I think this is what he should do. Forget trying to work in the mainstream. Go back to the independent press, or an imprint or something, and write "The Second Coming". Do it just like this, riding that line between ridiculous and kinda cool... if he wants, let him take it serious, the rest of us can enjoy the resulting camp.
I really, honestly want to see Rob Liefeld write Jesus wandering the Earth, beating up false gods, idolaters, and those who take evil actions in God's name and occasionally proclaiming "I kick ass for the Lord!"
