To make a good sequel requires a very delicate balancing act that few film-makers seem able to pull off. On the one hand, because it is a sequel, there has to be enough connection with the previous movie to give the viewer a sense of familiarity with what's happening. On the other hand, there has to be enough originality to the story to make the sequel worth watching. Unfortunately, "Grumpier Old Men" seems to fail the originality test. Having said that, this isn't a bad movie. Filled with a galaxy of old pros, it couldn't be. Jack Lemmon, Walter Matthau, Ann-Margret, Sophia Loren, Burgess Meredith these actors know what they're doing and they know how to hold a movie together. They do that here. The performances are excellent, and the movie's worth watching just to see the teamwork among them. It's in the story where things fall down.
You can only watch a couple of old men insult each other for so long before it becomes tiresome. John (Lemmon) and Max (Matthau) already spent the entire first movie doing that. "Grumpy Old Men" was a very funny movie, but listening to them call each other "Putz" and "Moron" has lost its appeal, quite frankly. Like the previous movie, the men of Wabasha are fixated on fishing, and they're still intent on catching "Catfish Hunter" a giant catfish who lives in the lake. Like the original, a beautiful woman (Loren) shows up in town and distracts everyone from the fishing business at hand. It all seems too familiar. Then, where there does seem to be promising originality, it ends up not being sufficiently developed.
I thought that the budding romance between John's dad (Meredith) and Maria's mother (Ann Guilbert) had comedic potential, but the two ended up only having 2 or 3 scenes together, and the "stop the restaurant" campaign could have been (and seemed for a moment as if it was going to be) the comedic centrepoint of the movie, but in the end, all we got was about 10 minutes of what were essentially vignettes of the various things John and Max tried to do to stop Maria. The romance between Max and Maria was not as interesting as the competition for Ariel (Ann-Margret) in the first movie, because there wasn't any competition for Max, and the other highlighted story was the romance between Jacob (Kevin Pollak) and Melanie (Darryl Hannah), and, to be honest, I just didn't care much about them.
I give the movie credit for the wedding twist at the end which I have to confess I didn't see coming, and the cast did a great job. Unfortunately they can only work with the story they're given, but on the strength of the good performances, I'll rate this as 6/10
