I think he would have spared us sequel apologists deflecting the fact that Finn is a walking racial stereotype.
Just think TFA:
- Black stormtrooper becomes runaway slave;
- Gets named by a white guy (sensible)
- finally turns out to be a space janitor mopping the floors
- Jives space-negro slang a la "Droid, Please!"
- gets called a thief and is electrocuted by white girl (in TLJ again)
- is generally inferior in abilities and character to white guys and gets lectured (Rey, Poe, Han)
- is disingenuous and chases after the white chick "Got a boyfriend, cute boyfriend?", REEEEEEEEEEEEEY!!!!
- shoots at child-soldier comrades with a lot of joy without remorse
- bumbling hysterical fool, drinks with animals and gets strangled by Chewie (like Lando).

But I'm generally ok with Boyega, he's solid with the crap he is given.
