Well, that's because it's the only musical movie of the summer.
They wanted to make a movie for the female gender, so if you're a male and you're forced to see this you better relax your butt and let it happen. The girls want to watch this to see Giulio Berruti, because he is handsome as ****. I'm a guy, 100% heterosexual, but if you deny that this man belongs to the top of our class, you are lying.
The acting is average. Every character looks like he is living in a fairy tale, so everyone is happy and starts singing at random and sometimes inappropriate moments. You notice that every actor in this movie is enjoying their work. They act playful and enthusiastic, so you can't help yourself smiling sometimes. The dark side of this acting style is that you don't take the more emotional moments very seriously. It's a happy-family-summer-musical-movie after all, so everything is going to be be okay. Oh yeah, the jokes are horrible though.
The movie itself is not that bad. I would call it a budget version of Mama Mia!, because the A-list actors were the main reason people wanted to see that. There's one location, one annoying girl and at the end a wedding with a 'twist' that won't surprise anyone.
It's extremely cheesy, but if you fancy a brainless movie night, this is not the worst choice you can make. Don't see it in theaters though, unless you want so see Berruti's abs in widescreen-size, and don't forget the alcohol so you can suddenly sing along with everything.
