Complicated? It can't be THAT complicated. Yeah, yeah, "programming is subject to change", and all that, but not like this. Surely, it's not complicated for a show to both start on time, and to finish before going to the next one (oh, and to show the closing credits each time). I mean, you can't just start a show at whenever time, you know? You also just can't broadcast one show then suddenly go to another. It's not like when NBC suddenly went to Heidi instead of showing the rest of that one football game back in 1968 (I understand that was a problem with the technology of the time). This is totally different. Sure, some people may be confused, but I'm pretty certain that there are others who know better.
I'm going to assume (for now) that they're not trying to sabotage their own block (and I certainly don't think they're trying to troll the viewers; that would flat out be totally unprofessional), so it's possible...repeat: possible that the people in charge of the block may not really know what they're doing. Another possibility (unlikely, IMO, but still possible) is that the people running the block may be in a position where the "higher ups" could suddenly demand last minute changes while one or more shows are airing. I certainly don't think that this block is just a publicity stunt to make the streaming services (or even the cable networks) look good. That would be the worst thing ever. One thing is certain, there's just no (real) excuse.
Look, everyone. If this keeps up, we may have to start getting answers for why this is happening.
