Dark Waters

It's painfully obvious that the underwater scenes are not filmed underwater. That's how we begin before cgi sharks make some cgi blood splatches. The sharks take an extended break from appearing in the movie and our heroes (a washed up Lorenzo Lamas, a strong female character who happens to be a statutory rapist, and bland man third wheel) have to evade two different groups while on separate submarines. The sharks come back but nobody cared by then. Truly awful.
