“Complete his training” is relative. If he’s already enough of a badass to freeze someone in mid-air with his mind at will,
It could be that little trick wasn’t even a Force power.
Maybe it was a piece of technology that created a "stasis shield " around an energie beam.Maybe is was a glitch in the edit, nope it was just as ridiculous as the rest of the film. I just got over prequelitis, now suffering severe sequelitis.
Even if you hate TFA, which it is your right to do, you can’t possibly think it’s even close to being as bad as the prequels. Can you?!
It has certainly drawn my attention to their much more original plots…but even if I did not wholly enjoy its substance, I did appreciate the feel of TFA…it was intended to be a more mature film than the prequels…
