What a pleasant surprise! And I submit for your approval...
Even if this ever-so-subtly tongue in cheek X-Files horror episode is a rip-off of a very special, and very old, Twilight Zone episode called "It's A Good Life" featuring a brilliant little Billy Mumy, as the main character; This episode, Scary Monsters, was still delightfully original, yet so 'Zoneesque', leaving the viewer a little creeped out. If you are a true Sci-Fi fan and have the time, I suggest that you watch this X-Files Episode, Scary Monsters, then watch the vintage Twilight Zone episode, It's A Good Life, starring Bill Mumy. It's my contention that this is the fertile soil that Scary Monsters sprang from.
That's as far as I can go without spoiling the whole enjoyable episode, so please just ignore the whiny naysayers raining on the later X-Files seasons just because they are mad about the missing Mulder, and won't get over it. Good Sci-Fi stands on its own legs without rock-stars.
Agent Doggett and Reyes steadfastly handle a most unusual case with the help of Scully and a couple of delightfully ditzy guests, especially adorable Agent, Layla Harrison, and her humble cuteness. Also: Keep your ears peeled for a clever, excellently placed "I Did That" within the script; a little wink to their standard closing credits. Are they called Easter Eggs or something? I don't know. But when they work, they work, and it's fun to be in on a little family joke.
Thanks X-Files writers and actors for cranking the winners out season after season. I'm sure your efforts were often under appreciated. Scary Monsters was a fun adventure, and I hope to be validated someday about its original grandparent in the fabulous vaults of the Twilight Zone.
