I know what ya mean!
Definitely makes you want to travel to Asia and drink tea in beautiful spots. I have watched it twice now and I think it really opened my mind up to a lot of things I really didn't know about.
The next one I am trying to find is "The Meaning of Tea". I think it is around 20 dollars U.S. on the movie's website. It is different than the other movie but it sounds really good. There is also a companion book on Amazon which I have been considering as well.
There is a great resource on this site called Tea Class.http://www.teaclass.com/
There are online lessons you can go through with little quizzes after them; which goes through all types of tea and related issues. I found it very helpful. Also, just posting questions and reading different threads on here has also been great.
