I'll get roasted for this, but here goes...

"Josie and the Pussycats" from 2001.

It was marketed wrong (IMO). It's honestly a really funny satire on corporatism, and celebrity worship, and everything that essentially turned up to 11 in the years since it was released.

The very definition of "came out to early to be appreciated" since it was skewering things that were only then just beginning to take over the internet.
