The first round of Ant-Man's press copies went out and here are some of the reviews. There's also a link to a (very) spoiler-y article about what is in the TWO end credit scenes.
Ant-Man is a different Marvel movie in scale (go figure!), but also a whole bunch of fun. Laughed a lot, and great performances all around— Eric Eisenberg (@eeisenberg) June 26, 2015
So I saw ANT-MAN & I dug it! Most inventive action scenes yet & tons of heart. A softer, more intimate #Marvel movie and a great family film— ErikDavis (@ErikDavis) June 26, 2015
Also re: ANT-MAN: There are two end-credits scenes, so stay till the very end kids— ErikDavis (@ErikDavis) June 26, 2015
"Ant-Man" is hugely entertaining, and a truly significant puzzle piece in the Marvel Universe. This one's got a big sweet heart.— ImperatorHitFixDrew (@DrewAtHitFix) June 26, 2015
It takes ANT-MAN a moment to get cranked up, but once it does, it’s sensational. My favorite third-act of any Marvel movie.— Jeremy Smith (@mrbeaks) June 26, 2015
I liked Ant-Man more than I did Avengers: Age of Ultron, mainly because Marvel's doing something different and it works as a stand-alone— Edward Douglas (@EDouglasWW) June 26, 2015
