Well, I would take user reviews with as much of a pinch of salt as industry reviews, just for different reasons.
Not that I'm in any way defending publishers like EA and Activision who have boundless funds for paying off reviewers as a default marketing strategy... You know, if they wanted to.
User reviews are rarely objective. You get people who are touchy about validating their purchase and so they automatically rate something 10/10, you also get bandwagon reviews that latch onto a particular criticism and underrate a game based on some single problem that may even be trivial. Fact is in any given field 90% of people don't know what they're talking about, they just want their opinions heard.
The problem is these are two opposite ends of the spectrum. Professional media company reviews or end user reviews. I find that the most reliable source of genuine objectivity is from alternative media, somewhere between those two. You should ignore GT and IGN, all of that crap. If you want a real review you want to look at alternative reviewers who are self employed or do it as a hobby, too small-time to be payed off but knowledgable and objective enough to be fair and honest about things.

Classic Game Room, I follow pretty much all of their stuff on Youtube, their reviews are awesome and funny, but most importantly they ring true about what the qualities and flaws are in the games.
