This will hopefully be the first of series of reviews of modern comics in this, the Conglomerate Age where everything is merely a drop in the corporate bucket which makes my opinion practically worthless. But you get what you pay for and we'll see if we get ours with Ant-Man #1.
As first issues go, it certainly sets up the character and his situation but it gives Ant-Man no purpose. He has no niche, no mission, no reason for being Ant-Man except to spend some time with his daughter. He needs more.
And we've seen all this from Scott Lang already. His conflict with his ex-wife and his being an ex-con were resolved ages ago. Except for some references this story could take place after his initial Marvel Premiere appearances. The maturity and leadership qualities that Scott possessed are washed away in order to present him as a wash-up!
And he doesn't even catch the villain! Iron Man does!
In recent issues of She-Hulk, Henry Pym shows up as Ant-Man while Scott was in FF. Are they sharing the identity? Hopefully Han will appear here to settle "who-is-who". They debut a new Ant-Man armor here and it's visually uninteresting and generic. They do give him a knock-out gas gimmick that's nice but he still lacks any sort of offensive power.
Then there's Cassie Lang, the apparently now-former Stature who is no longer dead (as Scott was himself). But she's no longer in the eighteen-to-twenty year old range but now looks about fourteen! It's almost like they gave him another daughter so he has something to fight his ex-wife over!
If this book is going to succeed, they have to give Ant-Man a challenge and some motivation. He needs to be more of a heroic figure. He can't act like a supporting character when he's the star of the book!
There's a bit more on the Malibu problem here under Potential Ultraverse Revival:
I just kind of hope this book isn't giving us a clue as to the tone of the movie. I'd hope for something a little brighter in the movie.
I would have expected something like Dr. Cyclops or Dr. Shrinker if they hadn't established there's already been an Ant-Man around for decades.
