> A negative review tells you what can go wrong, and whether that problem matters to you.

You accidentally made my point here.

"Whether that problem matters to you" is a matter of opinion. You apparently find the smattering of negative reviews to match your opinion; that's fine! But they don't match mine, or everyone's.

Opinion-wise, the movie seems to be doing just fine. This weekend we'll get the actual metric that tends to matter, the % drop-off after the first week. That tends to be a pretty good indicator of actual public opinion and word of mouth.

(And frankly, at this point, I tend to assume the negative reviews on Amazon are competitors review bombing. They're no more immune than the positive ones.)
