Really, I think some people try too hard to avoid the "humans with makeup" shtick. In doing so they might ignore the practicalities of form entirely or just use a single superficial reason to justify one of a dozen things. Halo does well, Mass Effect had a lot of very questionable aliens, not helping that a few of them were Humans with makeup.
