I'm not gung-ho one way or the other on the x-plus stuff (some look nice, others don't. I think they're too pricey for what they are).
But, I think some here are really being unreasonably harsh. The legs are right. That cut line on the shin (which is probably a result of the production process) makes it look odd, but look at it compared to the actual suit. The length is right. And the head looks pretty good too. And, you can't tell in that pic, but I'm pretty sure the forked tongue is right too (though I'm not sure why they made it so long). The antenna do look odd. I wonder if the actual suit's antennae were segmented or something & this is their attempt to reproduce it? The Bandai figure (which everyone, myself included, seems to think is well done) also has a sort of segmented look to them...
It's not perfect, but I think it's actually a pretty good representation. And I bet it looks better painted up. And again, this is from someone who has NO interest in buying this or any other X-plus figures. Still wish they'd release uncompleted vinyl kits of 'em though at about half the price. I'd be all over some of them then...
