I'd second that notion..
Once the public starts to see a dedicated F-35 demo team performing maneuvers other aircraft can't match, the criticism will begin to melt away. This of course, will bring up "which other aircraft"?
The American airshow audience is used to seeing F-15's, 16's and 18's. The F-35 will look demonstrably better. Now in terms of Russian birds, it gets a little more tricky... The SU-35 demos I've seen are VERY impressive. Less so though, if you consider the subtle nuances. Such as the ability to maintain power/speed into vertical after a 9g turn. Or its 20% better acceleration than most Flankers and still 10% greater than the SU-35. That's hard to demonstrate. The general public isn't this discerning. Nor is it possible to demonstrate how given its stealth, most of these maneuvers won't be necessary as it sneaks up on its quarry silently. There are others...
SA is difficult if not impossible to demonstrate in an airshow routine. Likewise for it's E/W prowess. Or its ability to generate a false target. Or its ability to target SU-35's with say, other aircraft's AMRAAM's or an SM-6. It has so many of these "hidden" advantages that it can't or won't show people, it's a real shame. But we know they're there.
Combat is the real test. And on that score, the F-35 is built for combat - not airshows.
