This episode was a little weird but also heartwarming at the same time. I knew from the moment Riker woke up and is filled in by Dr. Crusher that something wasn't "real" about the situation which rather spoiled things, although the suspense of "just what is real" will have you rethinking everything in the second half, and the resolution is actually rather touching. I'll give it away here: a little grey alien whose entire species had been wiped out by the Romulans wanted a flesh and blood companion, and chose Riker. Have to admit, I would have too!
