An anecdote but I've seen exactly that. Sites that stream foreign films that you can't buy using hosts that will open 10 tabs of ads the moment you click on a video, weird redirects, and a bunch of user-hostile stuff.
Usually I go to the network tab and pull a direct stream to the file hosted, but some even go as far as streaming using specialized clients that chop up the video and apply encryption (which I assume is easy to defeat but not worth the hassle when the whole point is to avoid the hassle of ads)
What you describe looks like the other type of shady sites. The ones that don't have any content, they just redirect you between fake pages and websites indefinitely. Sometimes it will ask to subscribe with your card or install a streaming software (always a malware). It's all a scam, there is nothing to watch.
