I guess my biggest criticism is that the film introduces all of these great characters- like Hobie- and then we don't get to spend much time with them; sometimes we only see them once. I think this film would have worked well as a miniseries, or even an entire series, which would have allowed for more character development and more complete and satisfying story lines.
So those are my thoughts on Hail, Caesar! I really had a good time watching it; it's eccentric and funny and also has a few honest observations to make about the film industry, though in a humorous way. It's definitely one I'll watch again.
