I abandoned the show after season 4. The fourth season was disappointing and sounds like the fifth might be a let down as well. The first 3 seasons were absolutely fantastic.
I disagree. Most of S5 so far has been personal stories, not space opera. I'm still finding it entertaining, but I wouldn't recommend the show to anyone on the basis of season 5.
I was bored by the cookie-cutter Scary Alien Machine Planet and weird physics in S4, but season 5 is a great improvement. It brings the story back to Earth and the Rim, with real people making consequential decisions.
For me 4th was boring and even more disappointing considering that, after all they suffered to open the portal, all that they found was a ruined, minefield piece of shit planet.
Fith is being a little more entertaining but also turning the back to the portal.
Edit: also there's sound in space. IIRC that wasn't the case in the first seasons.
Nah, it's systemic. At some moment there were some missiles. There's no way to explain that, unless you believe the missiles make a transmition to the ship that launched them, to say in their noisy missile language that they're pursuing the target :)
