Firstly, I'd just like to point out how beautiful this film looks, especially with its opening establishing shots. The camerawork and mise-en scene are on point throughout and really give an accurate sense of place and time.
However, whilst entertaining (if not a little slow) this movie does have some flaws baked into its script. For me, the Father is a well acted character with a lot to be uncovered, but his arc just doesn't progress as the film goes on, and too much is left unsaid about what is actually going on with him. Its arguable that the director leaves this up to the viewer to decide, but considering the films runtime and lack of any other subplots, its hard to excuse this lack of character development and closure by the time the credits roll.
I'd recommend this movie to anyone who likes a slower paced character driven drama, but isn't expecting too much by the films conclusion. Acidman is a perfect lazy Sunday watch when things to do are light on the ground.
