it feels more polished than the original, and while I know they recreated the original Sacred Heart hospital almost exactly on a soundstage it just seems different.

I wasn't thrilled with them breaking up JD & Elliot immediately, but that's probably because I watched the real finale (with JD watching his future at the end) just before the new season started. So to see them enjoying the happy future only for that to be killed right away was disappointing. But I'm sure it'll all be fine.
