you really don't understand cause and effect, do you?
Of course I do.
How you're trying to apply it in this specific case, I don't agree with.
You're saying because of a bunch of bad ratings, the movie tanked. I disagree. Because it looked like a crap movie, and had the elements I stated above, and may have not interested the audience of today (look at Minecraft, that's what the kids want now lol), is why the movie tanked.
The ratings for the most part are just the aftermath of it. Hell even the critics (who prop up these movies or video game studios) rated it poorly.
