Went and saw the movie earlier today as well. Definitely expected it to be worse, even if at the end of the day it's still a great deal below the books in quality.
As for those feats mentioned above:
-All of the speed feats mentioned above are almost perfectly in-line with Walter/Flagg's abilities in both the novels and the prequel comics. He's dodged and outright deflected Roland's bullets a few times before, and has the fairly infamous feat of speed-blitzing three trained gunslingers and turning them into dogs. Roland scaling to him and catching bullets, however, would be a considerable upgrade for the character, since in the novels (IIRC) he was slower than Flagg in terms of combat speed and had slower reactions as well, and never did anything even remotely close to catching bullets in the old media.
-Where would we write Roland's enhanced senses into his profile? Notable Attacks & Techniques?
-Would the casual disintegration feat fall under 'vaporization of the human body'? And if so, would that warrant an upgrade in Walter/Flagg's AP with magic? He already has some great magic feats in the novels (which I plan on addressing in a CRT on a later date), but as far as direct physical/non-transmutation magic goes, that might be the strongest direct attack he's been shown performing as of yet.
-Walter/Flagg's durability is another thing I intended to mention in a CRT, but I feel like it should be brought up now before we go about scaling Roland's AP to him. His physical durability needs a downgrade. He has no feats whatsoever that warrant Building Level durability, and Roland shooting him dead is even further proof that he doesn't deserve such a rating.
-From what I can tell, the mind/emotion manipulation is somewhat new, but it's almost directly akin to the animal manipulation Flagg showed in The Stand and Eyes Of The Dragon, where he was controlling entire hordes of wolves/weasels and forcing mice to sleep/wake/jump/etc at his request, respectively. The nature of the commands, however, means he now has several more ways to ignore conventional durability. (which is honestly really terrifying)
-Would possessing/controlling people from another universe be enough for Walter/Flagg to receive a range upgrade? As it stands, he already had an effective range of several thousand kilometers, but possessing someone from another universe is on another level entirely.
