Yes and no.

Old Trek episodes were easier to rewatch as and when they popped up given that they were mostly self-contained.

On the other hand GoT is a single long story arc, there really isn't much you can separate into their constituent episodes making to just rewatch a single one without understanding that episode in the context of the season.

DIS I think takes a middle ground approach. While the story is a continuous one I think the segmented story arcs, much like season 4 of Enterprise makes it easier to watch each arc as more of a movie. Mirror-verse arc is 4 episodes and still shorter than a single extended LOTR movie. The Klingon one takes a little longer but there are some standalone eps like the Mudd episode. Will have to wait and see how they handle season 2.
