I like playing Single Player sometimes, is it feasible to play most scenarios vs AI?

I am playing a great match in France '40 against a human opponent and having a lot of fun doing so. That being said, there are times when I like to play against the AI in hopes of getting some enjoyment out of different scenarios when I don't feel like being committed to more than a game or two against a human and playing at a slower pace. 

In general, are PzC games feasibly playable against the AI? Does anyone get enjoyment playing against the AI or even more than a human player at times?
