Do we need spoilers here?
Didn't know that was Gandalf.
Aside from that I agree, so far TRoP has been close to or better than expected. I'm not sure what people expected here but at any rate it's too early. You would't want to judge LotR based only on the initial chapter either.
We don't know if it's Gandalf. It's only speculation. He mimics Gandalf-isms from the movies (cupping a bug and talking to it), and generally looks like him. It could easily be misdirection for someone else like Sauron or maybe even a blue wizard?
