Yeah I think the story benefits from some humorous beats, but maybe not like that, in retrospect.

But if it were like he's suggesting, people would complain that those characters final(ish) actions were out of character and it would make no sense for them to do those things. Just because you can see something coming doesn't mean it isn't enjoyable to watch. If you saw two trains heading towards each other on one track you wouldn't look away simply because the you see the outcome coming. There's a difference between foreshadowing and being predictable and imo it's not good criticism.
