This was the deal breaker for me when first looking at Angular - loose coupling, progressive enhancement, accessibility and keeping code in its appropriate layers seemed to get thrown out for an attitude that everyone has JS running... it felt like a return to the days of Flash.

I could ramble for a long time about it, anecdotally; I have peers who use (and seem to enjoy using) Angular (all .net devs), and others who point out its flaws (front-end architects). I find it a very interesting discussion point.
