It doesn't top Red Dwarf, both you and I know that.
They went to the Nintendo school of sequel naming.
They actually did, they just didn't name it "SG-2". They called it "Stargate Atlantis". It did well enough, lasting for 5 seasons.
SG-3 aka "Stargate Universe" didn't do as well as either of its predecessors and was canceled after a single season.
Who would be portraying role of colonel Jack O’ Neil nowadays? For instance Richard Dean Anderson or Chris Evans?…etc.
