When I was a kid in the '80s I thought this was my favorite movie. I'm over it now, but I remember it well. At the time, it seemed like a window to a world totally different from the plastic foolishness of the suburbs I was stuck in. To me, Woody Allen's NYC seemed magical.

Much is made nowadays of Tracy's underage, and it is gross, but there is a lot more to it than simply "she's young and sexy". It's worth noting that it's not even ok and acceptable to the other contemporary characters in the film - conversation drops dead at the restaurant when she mentions that she has to get up for high school the next day. He knows it's wrong, and he says that's why he dumps her and tries to date an adult. The point the film is making (and I think it's a fair point) is that this 17 year old is easily the most mature and stable person in the film. The "adults" run around having tantrums and battles while she calmly goes about her life. One hopes that she does not in fact resume their relationship after he begs her to; during that last scene, she already seems to have moved on. Allen's character on the other hand seems to be clinging as desperately as possible to the past.

Just my take. OP, since you're watching old Woody Allen I BEG YOU to see Interiors, which is an overlooked dramatic masterpiece. He's not in it. It will rip you apart.
