This is a much more sophisticated episode than anything in the original series, but the ability to steal a guy's lungs seemed a bit much (just as Spock's brain was removed). What makes this work is that Neelix acts the way anyone would under his circumstances. The villains (if we can call them that) have ridiculous powers that are so beyond the pale that I never accepted it. The positive is that given this lunatic plot, it is still quite well done.
