When the script has systematic holes, the entire narrative falls apart and leaves us with scenes that are implausible from every angle.

You've got this very right.

I imagine they wanted to create a sense of dynamism with those camera movements, but, as you mention, it doesn’t produce the expected results.

In the case of this movie, almost all the attempts turned out weird (to say the least).

On the other hand, the “shadow villain” is a strategy I also don’t care for in films of this genre.

I actually think this is an interesting type of "narrative device", but only when it is well-crafted and firmly integrated into the plot.

I agree with you that casting a famous actress in the lead role doesn’t guarantee a movie’s success.

This type of strategy certainly catches the public's attention, generally speaking. However, it is just that and nothing more.

Financially speaking, it might be great for streaming channels (especially in terms of viewership), but for the audience... It’s a far too shallow "feature".
