I remember watching the cartoon adventures of “Mr. Peabody & Sherman” when I was growing up. I think it was part of the “Rocky & Bullwinkle Hour.” Judging from the trailer, the filmmakers are making it a lot more wholesome than I recall it being.
For instance, Mr. Peabody (the dog) and Sherman (the human) weren’t father and son.
Thinking back, I remember it being more of a “master and super-intelligent, passive-aggressive dog” sort of relationship.
This also explains why I vaguely recall Mr. Sherman being an arrogant, know-it-all douche.
