These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Filler: Nearly every review, positive and negative, bemoaned the heroin subplot that seemed like it came from a different movie than the comedic, gentle stuff with Mary, and wished it were excised altogether. Indeed, the film dispenses of it with almost a half hour left in the movie.
It Gets Better: The movie starts with a four-minute opening credits sequence followed by a rather pedestrian ten-minute birthday-bash sequence that both establish the men as free-wheeling bachelors, when it could've been done in about a third of the time. But stick with it.
Roger Ebert: It begins with too many characters and too much plot, and 15 minutes into the film I was growing restless. It spends a lot of time describing the lifestyles of three bachelors - Tom Selleck, Steve Guttenberg and Ted Danson - who share a luxury apartment and play host to a never-ending stream of girlfriends. We meet too many of the girlfriends, and too many of their friends. And then it's the morning after Selleck's big birthday bash, and on the doorstep outside their apartment is a basinette containing a little baby named Mary. From that point on, the movie finds its rhythm, and it works.
