I loved HSM 1 & 2 but this is ten times better. Saw it twice in the cinema and the atmosphere was amazing due to it being the final film. Still not sick of it and have already watched the DVD twice since I got it 2 days ago.
In the first films I loved the music but there was always at least 1 song which I didn't love. In the last one I loved every single song.
The budget is obviously a lot bigger for the feature film and used well - the outfits, camera work, sets and dancing is amazing , especially "Can I Have This Dance?"
