This whole part 1 and 2 of 1 season is dumb bruv. Just release the whole thing. I need more Spy Family! Back in my days they used to release 50 episodes in 1 day!
I can definitely see why someone would prefer Oregairu over MDUD, I love both. Oregairu is more in depth thematically and has great side characters. I just think the dynamic between Marin and Gojo is fantastic and there's already been so much development
I liked Hori and Izumi and when they hanged out with the family. It was an 8 until they started dedicating episodes to uninteresting side characters. Oregairu handled side character episodes way better.
Not trying to be the bearer of bad news but, Spy x Family (even with where it is at in the manga), could not have ended season 1 properly or with any proper closure.
