I think the position is meaningless in a vacuum, The Marvels wasn't considered a success despite being #1 at the box office in its first week. Why would Echo be considered a success at #4?
I already explained that -- because it's
not a vacuum, since we have more information than those two numbers. Statistics are only meaningful when placed in context, and we
have that context, the relative budgets of the two productions.
Echo cost a seventh as much to make as
The Marvels, so it doesn't need to perform as well to be considered a success.
It certainly could be, depending on expectations, but we don't know what those are.
True, but what we
do know -- that it cost a seventh as much -- is enough to let us form a reasonable expectation of the odds. Since the bar for success is so much lower, fourth place doesn't sound bad at all, so your skepticism seems excessive.
More importantly, it makes no sense to compare
The Marvels's theatrical box office with
Echo's performance on streaming, since they aren't competing directly against each other. So the way you've defined the question in the first place is flawed. If you were comparing it to
The Marvels's streaming performance, then that could be meaningful, but since it only started streaming two days ago, it's too early to make that comparison.
