The ratings and reviews on my smartphone are often paid for or are artificially inflated by anyone willing to pay review sites or reputation management firms.
I think you just need to learn to interpret the numbers. For a big Hollywood movie, anything sub-8.0 on imdb in the week after release (where the shill votes still aren't outweighed by the general population votes) is bad. Just for this week, this rule of thumb tells me for example that the "Alien: Covenant" is probably not worth watching, and "The Circle" is a disaster.

I'm not sure how I can learn to interpret something that's been manipulated by people with vested interest to promote their product or put down a competitor's.
The value from these sites stem from actual consumer ratings, not bots or the services themselves changing ratings.
