Incredibly disappointing. Poorly written, weak characters, overall a poor cast. Jean Ralphio just doing a toned down version of Jean Ralphio. Steve Carrell with a dreadful and unpleasant performance. Pretty much the rest of the cast being pretty weak. Only one I liked was John Malkovich, but then again I'd love John Malkovich even if he was reading a recipe book to me.
I just think it's a poorly written and badly executed show. I think the core idea just doesn't work, and the story was all over the place. I wanted to love this so much because of the names attached, but I felt it just got worse and worse as the season went on, and the finale was poor.
As an aside, I'm going to repeat something I've got stick about before on this forum: I reckon single-release seasons are a different art form from both regular TV shows and from movies.
A lot of Netflix shows (including this one) are designed specifically to be binged in one or two sittings unlike a TV series. But they're also designed to be split into neat episodes unlike a movie. The audience is expected to consume them in a different way from both.
As such, Space Force felt like a 5 hour movie with intervals. The fact it defied so many long held conventions is part of why it got such a negative reaction from critics, imo. It's a difficult thing to pigeon-hole and compare other output against.
I don't know who gave you stick about this, I think it's widely recognised and accepted that the way we consume content has evolved massively over the past few years because of the Netflix model. The fact that people are not appreciating this has nothing to do with the way it's meant to be watched, it's just that it's a generally speaking unfunny sitcom, with poorly written characters and plots. The only benefit of binging it is that its awfulness is limited to a couple of days of your life rather than a week.
