To those who are wondering what those "bad" schools are:
To say that some schools are universally "bad" is a little ridiculous. The AAMC (or maybe it's another governing body, but you get the idea) has extremely stringent regulations as far as MD schools are concerned. If any school even tries to toe the line, they get dinged, put on probation, and told to fix whatever problem they have. This is the reason why residencies consider schools in the US to be generally equivalent (a higher step score + higher grades will trump a better "name") but not so caribbean schools, which are not held under the same strict standards. However, for some reason SDNers tend to gang up on certain schools and declare them to be "bad". This year, I've noticed that phenomenon with GW and NYMC, mostly. Any "X vs Y" thread that includes one of those two immediately turns into an arena for SDNers who have "friends there" to talk about how much it sucks, and how the OP should go to the OTHER school, no matter what. It's this weird mob effect, but with med schools.
However, don't trust any of that. While some of them bring up decent points about why this or that school is bad, a more objective poster could probably come up with negative points to say about the other school as well. Your best bet, as always, is to figure it out on your own, by talking to students there and visiting it yourself.
Ultimately, a school's value is a totally individual thing. There are about 2 or 3 schools that I would never go to, and they're all top schools. I wouldn't go to them because of personal reasons- essentially, I think their mission is total bs, and having known doctors and students who went there, I wouldn't want to be one of them. However, it is a PERSONAL opinion. I have a couple of friends who are going to those schools, and while I think they won't become the kinds of doctors I aim to be, I kept my mouth shut when they told me. They're not "bad schools". They're just not my cup of tea. On the other hand, my boyfriend goes to a "low-tier" school and loves it. They have some big grants, and some of his professors are world-renowned, the teaching is great and the hospital is modern, but their mission simply isn't tied to research the way a lot of top 10 schools' are. He has no doubt that he'll become a great doctor there, and he'll get the residency he wants. And isn't that all that matters?
