What can I do to improve some of the clips qualities?

[MorganEX]

Hey guys, I need some help! The quality of some of the clips are really nice but some are just horrible!
We're thinking of refilming some of these parts before our final submission (class project).

However, we don't want to do that unless we are really 100% sure we cannot improve the video qualities at all... (It's weird cause they were all taken with the same camera)

Do you guys have any advice or methods I could try using? I use Premiere and my friend supposedly has the Apple video editing software.

Thanks for the help!


EDIT: Whoops, I meant to put this on Newbie/General Discussion forum, can somebody move it please? Thanks!

The concept is funny, but the narration doesn't work.
