SPOILERS AHEAD
The movie was not that bad, but it felt more like a parallel universe. The sequence of events, how things actually happened in the series, and how people and the Kwamis acted were slightly different. I was surprised that it was a musical, and it bothered me that the voice actress of Marinette, and the person singing are different. Tikki didn't feel as patient as you would expect her to be. Lady Bug doesn't do her signature Lady Bug move after fighting an enemy. There is no time limit to being Cat Noir after he used his cataclysm. Gabriel Agreste gave up his goals after knowing Adrian is Cat Noir; he didn't even bother convincing him to give up his ring so that they could revive his wife. Power of creation is used differently. Finally, Lady Bug was not so stuck up with the idea of keeping their identities a secret. She should still be careful. Though Hawk Moth is gone, the possibility of another villain arriving remains.
