How bad is it? It's a documentary searching for a subject, an angle and a purpose.
Should you see it? No, unless you're a huge fan of both opera and photorealism.
It might've seemed like a good idea to have a controversial photographer known for photos simulating children in horrible situations, such as the Holocaust, do an installation for the Israeli Opera's production of "The Dreaming Child." It wasn't. It should've been abandoned before too many checks were written. The fact that there's two competing artistic visions could've made for an interesting documentary, but there's no dramatic arc, just a mixture of talking heads and fly-on-the-wall footage. We don't learn anything about anyone involved except that we don't like them.
