I think getting the plot to a point where the reader thinks "How the heck could I get out of this?" is something writers should do because it adds to the suspense. It makes it more compelling because the reader is constantly processing while reading, rather than figuring out an easy solution and then waiting for that to play out. It keeps them enthralled. But making the plot too convoluted can end up like LOST where you're just thinking "Put me out of my misery."
In short, build the plot up to a good plateau where they're scared to jump off, but not so high where the reader wants to jump off to commit suicide.
