I rate this an 8.7/10 as Paramount Plus provides some, but not all, of the core elements that a streaming service should have. For example, you can make several user profiles, start watching content on one device and finish on another, and save viewing preferences in a "favorites" system.

 Aside from minor annoyances like the lack of a watchlist, Paramount Plus is simple to use. There is some 4K video available for premium users, but most of what you'll watch will be in 1080p. That's typical of on-demand streaming, if not very impressive.

The TV and movie library of Paramount Plus differs from that of CBS All Access in that it includes titles from other ViacomCBS networks. While you wait for the newer original material to appear, new users get instant access to a slew of great original series. 

The network content supplied will primarily appeal to viewers looking for episodes and movies they've previously seen and appreciated. The newly released movie who have already seen their theatrical debut would appear sooner on this platform than anywhere else.
