Strange ending
I've always felt the ending to this was abrupt, and tonally jarring. In the last 20 seconds of the film we see Burt shoot a guy out of a skyscraper, then immediately cut to kids playing on the playground with Sharky and Dominoe while a corny love song plays in the background. Then roll credits. It all happens in about 20 seconds, then that's it!
Besides that I really love this movie.
