I used to take them seriously a lot more in the past, but these days I kind of ignore the critics. They always either make a movie seem way better than it really is, and sometimes make a great movie look like crap. SO, I only watch movies that look interesting to me, and I don't focus on the reviews as much anymore.
What about you though?
Eh, somewhat, but not most of the time. I will check out movies I'm excited for, just to see how the general public and people are viewing it. I still watch the movie even if there are bad reviews. You have to consider that one persons opinion isn't always going to be yours.
