You really don't mind watching low quality content. Like if they are adapting from the manga it's fine, but lets be honest here like I mentioned when
@It is a mystery was posting about TYBW Pt 2. The pacing of this part would have been atrocious if it had the OG anime's pacing. Not to mention the animation quality would be noticeably worse.
Look at One Piece as an example. They still do the weekly shyt because it makes money. But the quality suffers as it adapts like 1 chapter per episode nowadays. Long running anime is great when the content is available and the studio doesn't feel forced to slow down the pacing. And unlike back then we get much more anime. Which is an issue in the industry, but in most cases you can find at least 3 shows worth watching each season.
