There was so much potential here. The central narrative - finding Dory's parents - was unavoidable. Any scriptwriter, nay, your neighbour or cat would have known this was the right step to take. The filler, however, disinterests me. Marlin and Nemo's subplots are bafflingly simple with no sense of wit or fun.
I've always been a fan of classic films, film making in general has always been magical to me. And nowhere does it's history lie more deeply engrained than Hollywood. I remember watching the That's Entertainment series as a child and being completely entranced by the snapshot into the archives and insights into what happened behind the camera.
