I agree that the "bullet time" doesn't add much. Its interesting, but that's about it. Once the novelty wears off, meh.
Regarding PitchTrax, I find it sort of distracting, I wish they would use it more sparingly. I also find whatever system we're using a bit inaccurate. I could just be ME that's inaccurate, but some of those spots don't pass the eye test.
