If what I've seen on social media the last day or two is any indication, most people really think ObamaCare is nothing more than "we give you health insurance." People have no concept for what might be wrong with the law, or what might be negative about it, or what kinds of problems it might be causing. They really think it's nothing more than the benevolent government telling mean old health insurance companies they can't turn you down and they can't charge you too much.
Some of that has to be laid at the feet of the media, who don't report everything the law does. Some of it is because people aren't that interested in the details.
