Yeah well all boards like and dislike something. Take category theory here.

Yes the "is it even worth it" thought may creep in with such philosphers, but then again it creeps in with anything you do. (Make enough money to live a comfy live? Why do stuff that makes more money and not something else want to spend your time with.) But I know that the fear of reading bullship is something a bit different. Still, I don't think there has to be a coherent intenion for there to be a valuable interpretation. Seems my author is dead.

I like the 3 or 4 lectures by this guy

but that may be too basic for you.

Representation theory is among the nicest theories to work with, and has many applications in combinatorics, (linear) algebra, and geometry - and many groups form smooth manifolds in themselves (Lie groups).
All that said, they aren't prerequesits of DiffGeo (let alone Analysis). In fact it might even help to know some diff geo to then get into Lie groups more enlightendly. The reason is that diff geo is taught w.r.t. less rigit requirments than their group theoretical counterparts and even if you got a metric, early on you tend to not need anything than groups over R.
