Yeah the matrix dodge was stupid... think of the scene like this..
Kylo swings at Luke, the saber goes right through luke, kylo looks confused and then figures it out - cut to real luke sitting there focused, in control (maybe even show a slight singe or burn on the area kylo saber passed) - cut back to kylo and he and then goes to just "walk past" luke and go get the rebels err el resistance - then luke grabs kylo and throws him back - cut to "real Luke" and show extreme exertion used to do that - cut back, Kylo stands up and starts to use the force on luke, his projection is affected by kylo (as he IS suppose to be powerful AF you know...) and then we need to see the resistance is almost out, but they find the exit is blocked...they still need more time.... cut back and luke breaks out from kylo and goes SSJ9001 and produces a huge blast of light and sound (this would be a better place to use the light speed attack result "art" in, vs when they did) - this causes everyone there to recoil and go blind/deaf for a little... cut to lukes death... cut then to mary sue saving them and proceed.
