Just noticed it's on Netflix.
Worth a watch?

Ehh.

Watch it once or twice

I held off for years watching but enjoyed it.  One error with the Marine sergeant who helped find the port authority officers.  Recommend it.

I was worried Stone would work an agenda into it, but I thought he did a good job with it. It's worth a watch.

I've noticed that Stone usually does two things with his movies. His puts out a leftist agenda(propaganda) and significantly alters historical facts to fit that agenda(propaganda). You say he didn't show an agenda with this movie. Did he significantly change any historical facts? I noticed that he did that with "JFK." If not, then I may be tempted to give this movie a view. I refuse to even view "Snowden" when it comes out on the cable channels. The previews make Snowden look like a heroic character.
