Pitch perfect was an extremely funny movie. Many people loved the movie resulting in a sequel. It will definitely be as successful because of consumers buying many products and watching and buying the money. Even though the movie might not be as good there will always be consumers who will buy products for movies.
Pitch Perfect is basically 'Sing It On' - Bring it On, but with music. That's a great formula, and the original film leaves the sequel a lot to live up to, but there's easily room for it to do so. Providing that the music is good enough, they've got such a brilliant cast that audiences will eat it up.
There's a lot of hype for the second Pitch Perfect, and people are really excited to see it. I think that the movie will do well specifically due to all the excitement that has been created through commercials and radio adds. The actresses in the movie are well known and appealing to multiple age groups. It will do well in the box office.
Pitch Perfect 2 will not be as successful as Pitch Perfect. This is because sequels just never amount to what the original film is about, either in storyline or monetary box office success. People rarely talk about how much they loved the sequel. And sequels rarely become cult classics like the first versions do.
It is a known fact that sequels are generally not as successful as their predecessors. Pitch Perfect 2 will be no different. The cast is popular and funny, but the premise is not as good. It may sell well initially, but the popularity will wane soon. It will not do as well in DVD sales or have repeat theater goers.
