>> This is about the worst methodology you could possibly use here.
By the contrary. It is the absolutely best methodology. I am surprised you cant see why.
You should do the same for hotel reviews or amazon products. Its about the CONTENT and nature of the bad review. The best way to judge a movie, hotel, or product is often to read the negative reviews first, because negative reviews reveal the failure modes. A positive review just usually tells you what worked for someone. A negative review tells you what can go wrong, and whether that problem matters to you.
You should always start with the worst reviews because they reveal the real weaknesses. Then you judge whether the criticism comes from an unreasonable person or from somebody thoughtful and fair. If the negative reviewer is intelligent, specific, and or balanced, that review is often more valuable than ten positive ones, because it shows the actual risks and not just the hype.
Use it for movies, books, hotels and amazon products...
> 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.)
A movie which doesn't satisfy your specific tastes and expectations in science fiction hasn't "failed".
