They've posted a couple more English-dubbed episodes of "Belfort and Lupin" to the YouTube channel. While it is still primarily aimed at kids and there is still slapstick, it's not as prominent as in the first episode I saw. It's a very warm-hearted show. The main couple -- and yes, I do believe they're meant to be a couple -- are so cute together. I like how they solve a problem in every episode (that I've seen so far), kind of like a cute little procedural. The English voice actors are very good, but sometimes it does have that "wearerushingtogetthewordstomatchthemouthflaps"
thing that's common in animation dubs. I watched a clip in French with subtitles and it's more charming.

Here's my fan art of Belfort and Lupin as Road Rovers:

I'm about to write a rant about "BoJack Horseman." I wanted to write something positive before I did that :D.
