ABOMINABLE SNOWMAN?

My 5-year-old son is quite the fan despite never having seen an episode of the show ever since I told him it was like Scooby-Doo for grownups. Since he took me literally, as he always does, he desperately wants to know what the "monster" is in the movie, even though he won't get to see it himself for six years or so. Using deductive reasoning, he now insists that the monster is an Abominable Snowman -- because they are in a "snowy land" in the commercials and of course the only monster indigenous to snowy lands is, of course, an Abominable Snowman. But now he won't stop asking me even though I told him I don't know. "Is it? Is it? I bet I'm right. When will you know? I bet I'm right." I finally couldn't take it anymore and told him I would just ask you. So tell me, Frank, is he right?
Seriously though, thanks for bringing Mulder and Scully back for us! I've missed them.

I am sworn to secrecy about the plot of the movie, but -- for your son's peace of mind -- I am willing to confirm it is NOT about an abominable snowman.
