Hahah! Well, I am absolutely glad you enjoyed it! Once you have made it a few times, the prep/cook time would drop quite a bit. In fact, I think it takes us about 45 minutes from start to finish, and that is with making 2 pies.
The recipe does allow for some deviation, so if certain parts need to be modified (like smaller chicken pieces) then it would not impact the recipe at all.
Anyway, I will be sure to let my dad know that you liked the pot pie, I'm sure he would be thrilled to hear it. Thanks for your critique, I hope others try it and like it too!
