If he just stepped back and kept his personality out of it would be much more tolerable.
With that said, he has been able to get in-situ interviews with rocket company CEOs including his amazing 2 hour almost single take video tour with Elon Musk [0] where I was able see Elon comfortable in speaking much more deeply, candidly, and enjoyably than with any interviewer/reporter prior. Tim Dodd is no professional engineer but he really knows his stuff. His personality helps bridge the gap between the highly technical and the layman.
Personally I love that Tim's personality shines through in his videos. His enthusiasm is infectious and just plain nice to see, IMO.
