I’m not sure if Mudbriar is an interesting character for the overall show. I think couples in movies or TV shows or videogames are more interesting when they are different to each other. For example, in Uncharted 1 and 2 you have Nathan and Elena (I haven’t finished 3 and I haven’t played 4). In WALL·E, you have WALL·E and EVE. In City Lights you have the main character and the blind girl.
Here, we have Maud Pie’s boyfriend who’s like Maud Pie but with sticks. Some scenes are kinda cute, but not enough for a 22 minutes episode. It’s a bit redundant.
It’s not that big of a deal to me anyways, but I’m assuming if someone from the Mane 6 will get a boyfriend in season 8 or 9, that boyfriend will be very similar to her.
And I agree that Maud Couple was better than Rock Solid Friendship, at least for little things, like the final message, which is great. My main problem with that episode is that it’s really boring.
