I liked this movie a lot. Part of what is so good about it is its unique story and style. It seems like so many movies tell the same old boring story over and over again. The ones that end up feeling original usually do so by telling the same old story in a new way. Hi, Mom! succeeds doubly, however, by telling an original story in an original way.
Additionally, a very young Robert De Niro plays the lead role very well, as always. This is a different sort of role than what we're used to seeing him in, but it's nice to see that even so early on in his career he was just as talented as he is today. His character is hilarious, often defies logic and leaves the viewers baffled about his intentions and decisions and wondering if he is a crazy person. The character is fun to watch but would be totally unbelievable in the hands of another actor. De Niro pulls it off!
Director Brian De Palma's inexperience is evident at this point early on in his career, but that's not a bad thing. I think most would agree that it was his later films that turned out to be the real stinkers, and his naiveté is put to good use here as it adds to the film's overall style and originality. The style changes to a documentary feel and then back again. Scenes are comically sped up and colorful intertitles are used sporadically. They at first feel out of place this far away from silent films, but then feel as if they could never have been more right. Just like a child learning to walk, De Palma is unsure what he can and can't do, and he doesn't care! He tries it all, and since he's not afraid to fail he only succeeds that much more. Unconfined by convention, he goes off instinct. The world is his oyster and he makes the most of it with what I consider one of his best films.
My favorite part of the film was the very last shot. I won't spoil it by giving it away, but it is totally unpredictable and unexpected, just like the rest of the film. I got the idea that the filmmakers could very easily have been making things up as they went along and not always following the script, making use of what they had available on their limited budget, which in this case worked out well. And the film's final shot is set up so well, from the camera angle to the colors to the overall setup. Then De Niro's perfect delivery to the perfect line makes it perhaps the greatest ending of any movie I've seen.
But the film is not perfect. Even despite its relatively short running time, it still feels slow at certain moments. It's a fun experience, but not everyone will enjoy it. Some may be frustrated by what could be perceived as nonsensical scenes and a disjointed, unrealistic plot. Some may not understand the film, but my advice to them would be to quit trying so hard. Just sit back and enjoy this fun, wacky movie and take from it whatever you will. It doesn't always make perfect sense or wrap up into a neat little bundle, but no one said it has to.
