I really wanted to like it. I think they would have done better to try to work out a plot that linked back to the show in some way- even just downsizing from that big house or retiring or something. The cancer plot was totally new and they didn’t really have time to develop it at all. Likewise Jake’s marriage troubles- he’s married and he has a kid but it’s not going well oh no actually it’s fine after all. There wasn’t time to start to care about it before it was all resolved.
I also think they should have included more interactions with children, not just hyena girl.
On the plus side, adult Ben was great- just really grounded and funny. Adult Jake looked like he’d been on the skag, not had a few sleepless nights.
