I do understand the point you are making. But it’s assuming a lot to think that most of the audience will even come back to give the changes a try.
Like I said, the audience always objects at first, to eventual successes as well as eventual failures, so it's naive to think advance opinions are the last word on the subject. I've seen this happen enough times to know that any opinion offered before the fact is worthless. I'm not "assuming" anything -- I'm arguing against making assumptions. My point is simply that we don't know yet and it's foolish to think we do.
And I
will give the changes a try, because I'm an optimist and I believe in giving things a fair shake before I write them off. I'd rather have a recasting myself (with the right actress), I recognize that this is a risky change, but I'm willing to give them a fair chance to prove me wrong. The very fact that they're willing to try something so risky rather than play it safe is worthy of respect.
Imagine if a restaurant closed during the shutdown reopened with a whole new menu and new chef. Should customers come back just for the same location and same name alone? Some might use the long reconfiguration period to find alternatives and never go back. Or lose interest completely.
Right, because people totally gave up on
Legends of Tomorrow when it stopped being about Rip Hunter and Hawkgirl. And
Babylon 5 when it replaced Sinclair with Sheridan.
Any major change can cost viewers, sure. Lots of people walk away from
Doctor Who every time it recasts the Doctor. But it's survived for decades despite that, because a change can bring new viewers in as well. These things are never exclusively about holding onto the existing audience, because any existing audience will undergo attrition over time anyway. TV and film series survive by catching the attention of new viewers as well as holding the old. And a fresh start or a bold transformation can bring new attention to a show -- look at all the press this change is getting -- and thereby attract people who weren't already watching.
Bottom line, there are both negatives and positives to weigh in a decision like this. The negatives you express are not without merit, but they're not the entire picture. I'm just trying to consider both sides of the question. Sometimes things turn out better than we fear. Sometimes they turn out worse than we hope. We never know which column something will fall into until it happens.
