This follows a pattern that Keaton would follow in a few of his most amazing films. The first half would just set up the situation and incidentally give a few mild jokes along the way. The second part is structured around a frantic set of stunts that are both comic and athletic. These must have astonished when they were new; its an odd thing that all the really interesting effects in films of this era were not for science fiction or action, but comedy.
Today, these effects and particularly Keaton's, astonish ever so much more. Jackie Chan is the closest we have now, or recently. Chan knows that when we see something that we know is real: Chan jumping off a helicopter for instance, and when that is done with a comic tone, for some reason we chuckle more deeply.
(Stephen Chow's projects are a twist on this. We know the stunts aren't real, but they are much more extreme, and they deliberately reference other movies.) This collection of stunts has Keaton take a large river steam paddlewheeler, a rig it up to operate the boiler room by ropes from the pilothouse. Keaton's agility is absolutely phenomenal: today such acrobatics would surely be computer generated. Its not obvious that the man is risking his life. But as with his railroad movie, it is obvious that this is a real machine in a real raging river during real serious wind, though the wind might be generated with machines.
This is big stuff, important to watch and real thrill.
