The first time I watched it somehow I came away from it thinking it was unironically good, but I was embarrassed making that claim and rewatching it with a different viewing audience as it's definitely more of the ironically good variety. Still, it's crazy, entertaining, sometimes stupid, and worth a watch with anyone who enjoys bad, campy movies.
It also is quite shocking as it doesn't pull any punches; I guess because it was a DVD release and not on a kids channel. When they kidnap the band members, They REALLY kidnap them, tied down, gagged, the lot. They drug a driver. They steal a car. And there's a scene where a main character attempts to seduce one of the band members; while the actress was overage she truly looked young and the character is a minor in the story.. so yeah. Gross.
Still, it's a unique experience watching an honest-to-god boyband kidnap movie, and I can't imagine not being entertained by watching this. And the film is nostalgic due to the time period; I think they really did capture the intense zeal that teens had for boy band members back when boy bands were still a thing. Oddly enough, this came out in 2007, in a period far removed from the N'Sync/Backstreet phenomena of 1997-2002 and yet far away from the future One Direction craziness of 2011-2014.
