Sometimes you can be a prisoner. Even as a filmmaker you can be one. You set up something and you set it up too tight. The walls close around you and there is no where else to go. The characters in this know what I'm talking about and once you've watched it (or very likely while you watch it) you will too.
The thing is, if you do a movie that is carried by this one "special" ingredient, it may very well fall short. But of course as with other movies (one comes to mind from the 90s, which had way better production values and way better actors in it) this can work for some. Those will just be entertained with what is being delivered to them. And if you can do that, without seeing the many flaws, that is good for you. Doesn't make the movie special though
