At the risk of contributing something to this thread, I’ll mention that I didn’t like Han shooting the bowcaster three times. The first time made sense (Chewie was injured) and Han’s reaction was funny. The second time didn’t make a ton of sense (although you could argue he was able to do more damage that way) and the reaction joke fell flat because it was basically the same joke as the first time. And the third time was completely nonsensical - why wouldn’t Chewie shoot the stormtrooper, or why wouldn’t Han use his blaster?
The point of the scene is to explain how Rylo Ken didn’t just squish Finn and Rey. The Bowcaster is billed as being really powerful and then Chewie shoots Ken loads of times so he has a strong handicap during the much moaned about final confrontation between them.
My issue was with Han using it again. Why didn’t Chewie fire the bowcaster those two times instead of Han? Sure he’s still kind of hurt, but then why is he carrying it at all? And don’t we see him fire it before Han does in that same scene? (Can’t remember for sure)
