Vudu is an option. You buy or rent shows a la carte. We watch several shows on Freevee (formerly IMDB) and Tubi. Both are free.
Same here. There is plenty to watch on those services. No need to pay for special channels at all. Also Newsmax is free, not bad for the price. Other free services include Plex, Crackle, and Pluto. I rarely watch those because Freevee and Tubi usually have more than enough to keep my attention.
We find Tubi almost unwatchable due to the number of repeated commercials. Same ones over and over and often.
They may be free but you still get annoying commercials.
