What film, show or game that is not necessarily 'underated' didn't have the level of social impact it deserved.
What's the antithesis of Arrested Development, Firefly or The Big Lebowski? Those may never have 'found their audience' but over time seemed to recognised by everyone. What are the deep cuts that you liked but it feels like everyone has completely forgotten they even existed.
Stargate. Had a long run with good viewership and multiple series, but has had very little cultural impact compared to trek/wars. Sg1 can stand up to any trek series
I always thought that Stargate: Universe was a Firefly situation. Maybe it was a touch below Battlestar Galactica, but it's not ludicrous to mention them in the same sentence.
Universe was my favorite of all of Stargate. It asked the best questions and showed how easy it is to die on a super advanced spaceship if there isn't fresh air and clean water. A shame it is discontinued.
It's been a long time since I watched, but people mention the way the world actually changes and grows as it progresses. In Star Trek, they use phasors the exact same way for centuries, in Stargate their M.O. completely changes from start to finish of the series.
