I have no idea if it is the end of the Big Bang Theory, but I think it would be super fun if it is:

* It doesn't have a negative effect on anything if it turns out to be wrong (other than some theses).

* It would be pretty cool to get a sense for how fallible we are

So I'm rooting against Big Bang Theory just for the experience of it :)

Depends what you mean by the big bang theory. The theory that the universe expanded almost from a point will probably survive forever, but ΛCDM might not survive the decade.
