Sounds like you and I are kind of in the same boat, mkilban. I'm not a comic reader myself either. Most I have is a couple of X-Men comics (sorry - don't know what series because they seem to have vanished momentarily in the mess of my room

they were somewhat 'newer' ones though, my sister had gotten them for free with some magazine subscription or something so she gave them to me).
I do, however, absolutely love comic book films - I mean, going back to when I was a kid, I don't think I can even begin to count the number of times I watched Tim Burton's Batman - even though I've never read the comics. So yeah... so far, the MCU films I think have done an excellent job at creating the interconnected universe but doing it in a way that also appeals to us non-comic book readers. I've been able to follow everything pretty well. Like you, I also learn some stuff through internet searching as well.
For the hard core fans, just want to say - the things you say make me intrigued, like when you were talking about the King Thor look - that's why I mentioned I'd be interested in seeing that (because as a non-comic reader, I have no other experience with it).
In terms of spoilers for this film? I don't think I'm going to try to avoid them. Some films I might, but with this one so far - the more I see and the more I hear - the more amped up I'm getting for it. I don't see any spoilers or anything decreasing that excitement because seeing things on my computer screen is going to be no comparison whatsoever to seeing it on the big screen with the theater surround sound. That, plus the fact that I have UK friends on twitter that I know will be seeing it before I can, and I don't think I can bring myself to avoid twitter *lol*
So yeah... just another thought from a non-comic reader but definitely a comic film fan
