Is it ok that comcast took the ideas for their new ad campaign from the movie Juno?

The new commercials show a song that resembles the songs by kimya Dawson. It's just weird.





It's the ones where the girl sings while going through her city. It's all in cartoon.





The ';dream big'; thing is also from Juno.








Idk help me outIs it ok that comcast took the ideas for their new ad campaign from the movie Juno?
If the commercials are different enough from the original work then there is no violation. If there is a violation then rest assured that the studio that owns the rights to Juno has an entire team of people looking out for this sort of thing.
