Not to get bogged down on the debate here about this, but I just wanted to say that I absolutely agree with this point. I think face characters of live action actors look so dumb because they virtually never look that much like the people. Characters without faces (masks, etc) or ones from cartoons work much better. I think it is better served for M&Gs to be masked characters/aliens/droids - still gives plenty of opportunities for Star Wars.
Personally, even as someone who likes M&Gs, I wouldn't waste my time lining up to mean cheap knock of cosplay Luke or Han or Rey. And same goes with Marvel. It's one thing to meet a masked Spider-Man, Iron Man, Captain America, Black Panther, etc. but another to meet a face character like Captain Marvel, Starlord, etc that don't quite look right. YMMV.
There's a reason that Belle in the parks doesn't attempt to look like Emma Watson
