Well.....I already have the rest of the League on PO because my intent is to assemble the JL. I honestly really don't want to get this figure, but I almost feel like I need it now in order to complete the League.
The only thing about it that says "JL Superman" to me, is the slightly lighter suit. I'm a bit disappointed that the normal sculpt is merely a repaint of the BvS sculpt. Even the hair isn't parted the correct way. I was really hoping they would do a different expression with a subtle smirk to reflect the change in tone, since they have used the same stern expression on all of their Superman figures now (including Reeve). The heat vision sculpt is a nice addition as I know people were always clamoring for a separate heat vision sculpt (though I think if you got that OSK heat vision sculpt that was perfectly fine), but that seems like it'd go better with the BvS figure being that he used heat vision more in BvS than he did in JL. Nothing in either of these sculpts really conveys JL Superman to me and nothing about this figure distinctly separates it from the BvS figure to where one is clearly BvS and the JL.
Perhaps someone later on creates a sculpt with a more ideal expression for it.
