Ran up a building and across water. Now he just needs to vibrate through something. Also: More Grodd!
I will probably get the raspberry for it, but I would of preferred if they hadn't done the "run up the wall" bit.
Over water, yes. No problems with that. Running up the side of a building is just flat out impossible using
just speed. Without gravity (or really sticky shoes), the first time he took a step he would no longer be in
contact with the side of the building and fall. Yes, I know the comic book Barry Allen could do it [although
Wally as the Flash couldn't], but the comic books even state the Barry Allen wasn't really human anymore;
that he was basically condensed lightning and didn't have to obey any of the laws of physics.
Personally, I would of preferred if they had gone the route of him running up 20 flights of stairs in the blink of
an eye instead.
On the other hand ... GRODD !
