Anyway, getting back on topic....
As much as I love George Carlin as a narrator on Thomas, there were some renarrations (stories Ringo previously narrated in the U.S.) I really didn't like.
Some examples: Thomas Comes to Breakfast, Duck Takes Charge, A Proud Day for James, Double Trouble and A Cow on the Line.
Ones I personally thought were really good, on the other hand, include Terrance the Tractor, A New Friend for Thomas, Percy Takes the Plunge, The Flying Kipper and Thomas Saves the Day.
I also didn't like the way his voice sounded in season 4; it got more gruff and nasally, almost like all the drugs he did were really catching up.
