Watching a random ep is fine, but when you sit down to do a complete rewatch of a show in consecutive order, its hard to skip eps on DVRAB, even if you know you hated the episode.
I simply cannot do it. If I am to watch through a show again, I HAVE to watch every episode in order. If I skip an episode, it just feels wrong or something.
With DB Kai for example, those fillers are already gone, so you wouldn't be skipping anything on the DVRAB, thus feeling like you're not missing anything, even if you know what was cut out.
