I've been watching a lot of stuff on Prime recently, I'll start with what I appreciated the most
Star Trek - Picard
Now, if you are even remotely a fan of Star Trek, you need to see this. Don't get me wrong, it's nothing out of this word, but it's a mature show for people who has grown up with Star Trek (TNG, VOY, DS9 and maybe even ENT, but that's already another story). Protagonists are disillusioned, things are far from being perfect, much far.. still hope never went away. Season one had a solid plot, nothing exceptional, but enjoyable. The finale, just wow, broke my hearth.
Season 2 is gonna have Q and alternate reality, should be more action oriented that the first one.
