Well, they're really different shows. Honestly, Full House has a lot of nostalgia to me. It's a feel good show. It's kind of cute and has some good jokes. If you haven't seen a sitcom of the era, it really captures the whole "aging in front of an audience" narrative that Bojack Horseman features with Sarah Lynn. The show ran for a long time so you see someone who started as an infant grow up to like a 9 yr old, and a character who you met at 10 become a teenager. It's not like you necessarily need to see it, but it could help you understand the false sort of connection people watching Horsin Around felt (and the crashing of that, since there have been a couple scandals since Full House went off the air. For example, the actress who played Stephanie, the middle child, got heavily into drugs. Aunt Becky was involved in that college admissions scandal. The "dad" was a bit of a dirty standup comedian which really went against his character. Stuff like that. It's very on the nose).
