Not ashamed to admit I went to watch this. For any followers of the Mark Kermode and Simon Mayo Film Review, I'm very much like Mark in the sense I can recognise the technical flaws and story issues, but to hell with that, the ABBA song's are too indestructible not to enjoy the film. Was never a fan of the blue/green screen backdrop to the hotel though; it stood out like a sore thumb in the trailers and similarly in the main film.
Don't think I quite enjoyed it on first viewing as the first film, mainly since I had barely heard half the songs used in this film, but given i've now listened to them multiple times on YouTube, I'd put a bet on me probably enjoying it more the second time around.
