“The thing about sequels” is a bad way to start a review. Cause you’ve most likely already read a review that starts like that. And you’re not reading this review to listen to someone compare two movies, or draw similarities between all second installments. You’re not reading this review to hear someone’s boring old opinion on the state of the film industry. You most likely just want to know whether Finding Dory is a good movie, or at least worth the time and effort it’ll require to see it in cinema.
