Without saying TOO much about the reviews, they've been saying Black Panther and Spiderman are the best parts.

It's better than nonstop reboots.

It does look very good but please not Spider-Man 2 good!

Biggest storyline in the Marvel universe so far. From the early reviews it seems they won't screw it up. Hype

I'm in the minority but I never understood the praises that SM2 got.  I thought it was horrible and I loved the first.  That uncle Ben death scene made me almost cry!  The second one? I cringed so much.  

This was completely expected.
The Cap movies have been some of the best MCU has put out. And now that I think about it, most of them aren't that great with the exception of:

Guardians
Ant-Man (this one's mixed with fans)
Avengers (the first, Ultron was awful)
Captain America 1, 2

All others have been relatively mediocre in my opinion.

You are sin.

I don't know.  I think many like infinity Gauntlet and Onslaught (amongst others) are much, much bigger.  It was one of the most financially successful crossovers in recent history, though.

I think movie makers that read comics from the boom in 1992 to maybe 2006 just know these major stories (Civil War, Age of Ultron, Knightfall) and possibly a couple from the 80s (Watchmen, Dark Knight Returns, Days of Future Past) and are quickly trying to adapt them to the screen.

I appreciate the changes that have to be made for Civil War.  That thing was over 100 issues and featured maybe 1000 characters! The trailer makes my balls tingle.  Hope it delivers for me.  After "Winter Soldier", I was left in awe. Only a few comic films have done that for me.

Doc Ock could talk to his tentacles.

HIS TENTACLES.

I never really understood the criticisms for Ant-Man. It's a Superhero movie with an overall heist theme. The acting was good, pacing was great, and Michael Pena stole the show! Not THE BEST superhero movie, but definately up there for me.
