The hatred for MongoDB mostly comes from the PostgreSQL supporters camp. The rest of us are just using whatever tool makes sense.

MongoDB is the fastest database I've ever used. The easiest to get running, stable and scaled out. The best documentation by far and has excellent integration e.g. Spark, Hadoop.

If you are doing Big Data it's a great tool in the arsenal.

It's fast because it doesn't actually save your data when you ask it to. It saves it later, when it feels like it, maybe. Also, the hate I have for Mongo is from first-hand experience with the wretched thing. The scaling is insane. The next jump after your first server is like 9 servers (2 repsets w/ 3 servers each w/ 3 config nodes). I don't have that kind of cash laying around for servers, especially when instance-for-instance, Postgres can handle easily 10x the write load of mongo.

RethinkDb does all of this better, and with good engineering and API design behind it.
