Yes, unfortunately, it is almost more important to reject the bad papers. The good papers will be published regardless of the reviewer. It takes more work when I get a bad paper, especially when it comes from someone famous, because I have to make a convincing case for rejection. I've even gotten the same paper multiple times from different journals (after rejection an resubmission). It's hard work to prevent flawed science from being published.
