10m opening off 28m budget

Good question.

It got a decent promotional push, too, I think. People complain about all the sequels and remakes, but it can be a struggle to get them to show up for something new.

This seems like one of those movies that'll do well streaming, at least.

28 mill budget is pretty low - the acting/sfx were all decent enough - I imagine it will make its money back

200 mill movies are generally money laundering operations -

Opening weekend is irrelevant! $35m WW on 3rd weekend.
