I know this is a very old comment but it’s kind of interesting right now as Marvel decided (suddenly I believe) to show 2 episodes back to back of Daredevil because they were losing viewers and they thought a double week would pull people back in.
I think it depends a lot on the show. Some are written to be dumped all in one go and be binged on a long weekend, others (like severance) are better when you’ve got a week to digest and analyse the episode and get excited for the next one.
Binge watching shows does cover up a lot of bad decisions & writing IMO, because you don’t have time to really pull something apart critically when the next episode starts in 10 seconds, but it also really highlights when a series is too long or has too much padding. A lot of the old 13 episode Netflix originals could have been cut back to 10 and been better for it -and when you’re on your 3/4th episode of the day you feel it. Some of them just dragged on.
I think the Amazon LOTR show would have been much better received if it was released all at once - a lot of the criticisms and complaints of both seasons were answered later on, but fans had 6-8 weeks of complaining about it before the show resolved those complaints, and if it had been released at once people would have seen the whole show before judging.
