If you don't have Paramount, Pluto plays Star Trek Strange new worlds, which is free. Thats the thing about Pluto, they show you the same episodes of Star Trek, Andy Griffith, twilight zone etc over and over, so you buy Paramount, to watch whenever you want. I got suckered in. But Strange new worlds is worth it though. Hulu has Lost In Space, the original series. The first season of Lost in Space is outstanding, then they veered off and once it got in color it was trash. That was before Star Trek. I dropped cable all together and just doing streaming. The only thing I pay for is Disney+/Hulu, Friendlytv for metv and history channel, and paramount in addition to my Amazon streaming. I guess its cheaper than paying cable. 1100 channels I never watch. The trouble is when football season starts, thats when they really get you. You might as well go to BWW at that price.
In hoesty I really think four seasons is enough for any series. Look at any tv show they drop off after 4 seasons. Srar wars goes by that platform. I don't know what they'll do for season 4 of Mandalorian. Mando can't just retire, that's lame AF!
But speaking of Lost In Space, Think it should have ended the same way Swiss Family Robinson ended. Earth finding them, establishing John Robinson as Governor of a new colony, and giving Penny and Will the choice of staying or going to University. The way it ended was hopeless. I guess that's reality.
