Finally someone who agrees with me. I like Backbone quite a bit and a large part of our application is now using it... However, the added code, layers of abstraction, and lack of any "right" way to do things make maintaining it more of a hassle than anything else. I like that many people are trying to build application frameworks on top of backbone (marionette, etc) but this is just making things worse as now you have 20+ choices on how to write your backbone application, thereby making it harder to maintain across developers (what are the chances the new guy you hired is not only proficient in Backbone, but also backbone using handlebars instead of underscore, and also backbone + chaplin -- or vertebrae, or thorax?)
When our js guru started porting our app the backbone, it was intensely difficult at first for the rest of our devs to make trivial changes to our front end code. What used to be a well defined information flow was now spread across dozens of files.
Don't worry, there will soon be a movement to get back to POJOs (Plain Old JavaScript Objects) and the cycle of engineers over-thinking a problem will be reset.
