It's true the movie was executed extremely well. It's well balanced and the tones are all fitting for the characters and story. I would've welcomed a touch more seriousness and weight here and there but that's just me because I always like a bit more darkness and grit; just a personal preference but not saying that movie desperately needed it.
I just got back from watching it in 3D, in a more mellow/not packed theater and I enjoy this more after every watch. I could easily go for a 4th time.
Not that it could be compared, but I see how it could be said that this is the Star Wars of the MCU. The Thor movies gave us a look and an idea of what's going on out there, and this expanded it further to give us a deeper sense.
Not much to not like. Good action, enjoyable characters on the team and they way they interact is great, the comedy works (maybe even better than any Marvel movie thus far), great settings and landscapes. The overall story could've used a little tightening up here and there but all in all a cool frigin movie
