I would like to know what does "gesture toward their own stagy conceits" mean here:

Nolan’s movies are often about people doing their best to get back in touch with consensus reality — against our tendency to be swept away by delusion (“Inception”) or demagogy (“The Dark Knight Rises”) — so it feels organic, rather than gimmicky, that they would periodically gesture toward their own stagy conceits. Where the villains of Gotham often seek to introduce mass hallucination, an involuntary susceptibility to somebody else’s powerful fiction, Bruce Wayne creates a symbol that campaigns for voluntary belief and action — just as Nolan does.

Thank you.
