Yeah, I see no reason to add a hand. lol
And I hate to be a wet blanket, but Rey using lightning on Finn doesn’t strike me as feeling right for that moment. It could’ve been scripted that way, but with what we have to work with Finn still flies backward and Rey doesn’t blink about any of it.
Yeah I’m not a big fan of Rey using force lighting on Finn, feel like it would probably look weird especially since ILM force lighting is hard to replicate unless you do it in Nuke
