Ian--I agree, it's a middling film at best. My take on it is that it veered from comedy to drama & gets too close to ultimate tragedy. It's too much to take, the swings in mood from scene to scene. It's like "The War of the Roses" (1989), which was promoted as a romantic comedy--as opposed to a comedy about divorce, & what a couple will do to each other in the process--it's a good film--see it some day.
Your camera presence & confidence is fine--no real criticisms to make
