Season 5 continues to deliver!
4 January 2011 | by (United Kingdom) – See all my reviews

Folie a deux is another strong episode from the great season 5. Its an episode that doesn't always get loads of fan attention but that doesn't stop it from being a good one. Not only that but at times the X-Files kind of forgets about being scary, and, well, just isn't. This episode I'm happy to say has a few decent Mulder and Scully moments, quite a chilling ending, and a fair few scares. There's some great shots, where, without giving anything away. There's a shot of someone, their looking seemingly normal, then a dramatic music note, it shows them again and things aren't quite how you first thought. It's in a way predictable yet its dramatic and effective. A great more scary episode from the already strong season 5. Folie A Deux is a good one, don't miss it!
