I don't think that's Xen's biggest problem. I think it has to do more with uninteresting environments. You go from cool offices that look like offices, crawling through vents and on top of ceiling tiles and into flooded rooms and electrified pools and all this interesting stuff... to barren flats and floating islands, but nothing there is really interactive, or makes a real world kind of sense. The best thing about the aliens is when they're shocking and new. But only the bosses in Xen are things you didn't already meet, so the impact is probably a bit diminished.
