You can watch it. However, I do not recommend you to watch it at a get together because there are far better movie options than this one.
SPOILERS AHEAD!!!
Umm... About the film... It was umm.. Good? No, it was, uh... It... didn't quite meet the expectations! There, I said it. Yeah, the animations were pretty cool. I know that it was pure hard work making the animation look so real. But, uh... The plot... There was not... It was not a good story... I mean, yeah, Mirabel was a strong and bright character but the whole story was so rushed. The starting was spectacular. I mean, it had the sense of mystery and all but the story started falling after Mirabel found out that the Calista was "cracking". The problem with the plot was: a lot was thrown in, in a short amount of time too! And it didn't make any sense. The songs were melodious and fun, though. The film symbolized that "black sheep" in families and out are not "ceptional" but "Gifted" in their own way. Aaand...That's good enough for me.
