My rule with critics is that if it's a movie like this that I want to see, I usually don't bother reading the reviews until after I've already seen it. I do read them, but I'm not dependent on them because my mind is pretty much made up about the movie already.
If it's a movie I'm on the fence about, I'll check RT to get a consensus and usually make the decision from there.
The thing with RT is that sometimes a movie rated 'fresh' isn't all that positive, and sometimes a 'rotten' movie wasn't so much a rotten review. I can never really tell how they score them the way they do.
One of my favorite movies was The Fountain, and that got a 50% on RT. And that's just wrong.
But I've been going to movies long enough to know what to expect from critics (and I'm not seeing any surprises with what's happening with
Wolverine so far)...sometimes I agree, sometimes I don't. I'm still seeing the movie on Friday night.
