My son who is 3 is not a lot into Bob the builder. But I don't like it because i don't find it logical machines trying to save birds and trees all the time. It is all about environment, I am not saying we shouldn't care, but having machines talking about it sounds weird. I feel there is a political correctness about this program.
My only concern is the sterotypes ... poor Mr. Sabatini has the worst Italian accent I've ever heard.
Just have to point out - Wendy is not Bob's wife (although i think she has a secret crush on him). Also, if you hadn't noticed, it's British and dubbed with American accents.
Bob is one of the best kid shows on TV. The "working together to get the job done" message is REALLY hammered in but it is worth it. Our son even says things like, "We need to do teamwork, like Bob!"
