If you typically like Bakshi's movies, this may not be a good one to start off on, nor likely one to watch at all. It is missing the artistic beauty of American Pop and the comedy of Hey Good Lookin'. It is jammed pack with a confusing story about sleazy city dwellers.
The movie combines live action and animation, though the majority of the film is animation. It opens with a scene at an arcade, and Mike, the main character (both in the live action and animated segments) is playing a pinball game. As situations arise in the film, we are constantly referred back to this pinball game in progress, thus being forced to find the connection between the two.
There are a lot of different characters here that all impact one another, eventually becoming one story. Mike is a cartoonist. His father is involved with the mafia. His mother is a drunk who wants to kill his father. His friend is a transvestite. And, he eventually picks up a former hooker/bartender as a girlfriend, and together, they're going to figure out how to get enough cash to get the hell out of the city and move out to the West Coast.
The story is confusing however, not only in the amount of characters you have to keep track of and their place in all of these interconnected events, but often, you are confronted with scenes without dialogue or some that don't seem to connect to the rest of the movie. Plus, there's a whole lot of people just looking to get laid, so there are a lot of naked cartoons running around, which is a bit frustrating when you're looking for more, not less, to help you figure out what the heck was going on half the time.
Not to mention, once the cartoon story ends (consequently along with the pinball game), the live action story continues. Even though the fate of those live action characters were decided in the cartoon universe, it gets contradicted in what seemed like an unnecessary ending that also occurs in the live action universe.
Bakshi cartoons are known for excellent animation, especially as you see it in American Pop, but Heavy Traffic, while fitting for it's day, doesn't have that same beautiful artistry as American Pop (even though there is about a twenty-five year difference between the release dates of the two films). I suppose, being one of Bakshi's earliest, it was more experimental than the later films. And it was one that I found difficult to appreciate.
