This is the whole point of reviews I feel - you get to know a reviewer and you can use their review to decide if you want to see it. They may absolutely hate the movie, but the way they hate it makes you know you'll enjoy it.
"Review aggregators" have killed much of that I feel.
I assume there's also been a fairly dramatic falloff in professional reviewers given the state of newspapers. Not that people writing reviews as a hobby or as a twenty-something working for pennies for the "exposure" can't do a good job. But you're probably going to get a lot less consistency if nothing else.
True, back when newspapers were a "every city has one or two" there'd often be a local reviewer writing for that paper. Then it went to syndicated reviews and now I'm not sure I can even name a single reviewer.
Also, you have access to much more information about a movie if you want it, instead of having to figure out if you want to see a movie based on three inches of column.
