Can't wait to get to Season 3, granted, I still haven't got to Season 2 yet though, so I'm looking forward to that one first. With that said, in the past, I've just marginally been interested in the Marvel Cinematic Universe by casually watching most all the main movies, but never really connecting all the dots and getting super into all of them.
Well, after seeing Ant Man and being pleasantly surprised, I figured I'd give it a full shot. So, what I've done over the past few months is working through the full-out straight-timeline entire MCU experience, including all movies, TV shows, and even all the official-tie canon comics. The following is the best timeline I could find which was all-inclusive, so I've been following it to a "T":

I've gotta admit, it has been a TON of fun, especially just following all the intricate details. Plus, I sometimes just like to nerd-out on stuff. The comics are a lot of fun as well as they elaborate a lot more on back-stories as most are some kind of prelude. With that said, I'm not totally caught up yet, as I just watched Guardians of the Galaxy last night, and will be watching Daredevil next. This means I've also got, Agents of Shield Season 2, Age of Ultron (I actually have not even seen this yet at all), and Ant-Man left. Of course, those will soon to be followed by all the new stuff coming out very soon (mostly TV). Now, give me a few weeks to knock Daredevil out, and I'll be diving back in. Can't wait.
Sorry for the tangent, but back to Agents of Shield. At first, I thought the show was a little corny, the action was terrible, and a little too not movie-like enough. Granted, I still see those things to some extent, but over time, I grew to love it. The first half-dozen episodes are definitely slow for sure, but eventually the characters start to draw you in, and all the twists help as well (mostly corresponding to the movies). Hoping the next couple seasons do a lot of the same or better.
