There are great shark movies (Jaws), very bad shark movies (Jaws: The Revenge) and shark movies that are probably bad but are great in part because they are bad (Deep Blue Sea).
In fact, The Meg is now second only to Jaws as far as shark movies go at the box office.

It then makes the point that The Meg toes the line between being the right kind of bad or the bad kind of bad.
