The Netflix app shows what they have so we could subscribe when we see a few movies we want to watch. Netflix blocks VPN users.
Ads? Just watch them on desktop Chrome with uBlock Origin or Adblock for Chrome extensions - all ads are suppressed! With iOS 15 and Safari extensions, it may be possible to suppress ads on mobile devices too.
Tubi TV
Tubi TV is ad-supported playing a total of about 2-3 minutes of ads in a 2-hour movie. You can find movies like Rage (was there on Netflix before but not anymore), Troy, etc. here! A whole bunch of martial arts movies, too.

Peacock TV

Peacock TV, by far, has the best collection in high quality next to Netflix!
NOTE: If you have Xfinity, Cox or Spectrum, you get Peacock Premium (worth $4.99 per month) for FREE ! Simply authenticate and authorize Peacock under your Account Profile through any of the above services.
For Xfinity, you can stream on their free Flex box, browser or the app. However, I found watching Peacock with uBlock Origin extension on Chrome desktop suppresses all ads and makes it ad-free! The browser version works only on the desktop/laptop but not on tablets/phones which means we need to use the PeacockTV app on mobile devices and it shows ads. Flex box prolly serves ads too.
Peacock TV has plans starting at Free - no credit card required.
Watch 40,000+ hours of hit movies, TV shows and 50+ always-on channels for free!
More content and ad-free for a small fee.
You can find the MONK Series here - 8 Seasons (was there on Netflix before but not anymore).
