Honestly, a preview for another show on the same service doesn’t bother me AS LONG AS it is skippable. I’ve never used paramount so I’m not sure if that’s the case.
If I’m being honest when I was a kid part of the fun of going to the movies was the previews before, finding out about upcoming movies and what not.
I do agree that you shouldn’t see the same preview every episode cause that’s super annoying. But I’d be totally fine with one per session or something. Again, as long as it’s skippable right from the start.
