The fact that several teams of very highly qualified physicists bothered to look at it makes me believe the physics involved is non-obvious and can't be written off with a simple "the theory is simply wrong". Dismissing it out of hand does a disservice to all those people.

That's not to say it'll prove to be true, I doubt it will, but this is something that has so much potential it's worth investigating the tiny possibility that it's real, and "all currently used theories of electrodynamics are wrong", just in case.
