Sorry, I have been busy but, yes, I did see it on Monday this past week.
I say yea. It is not quite in a class with the best Marvel movies (Cap 2, Avengers, Guardians, and Iron Man) but is as good as the Thor films and better than Iron Man 2 or either of the Hulk films.
It differs from other Marvel movies in that it is more of a comedy caper than an action film. I laughed out loud more than I was thrilled with some stunt or special effect sequence. The story is pretty good, though it lags a bit at times. Things get a tad ridiculous late in the film and there are some "why did they do that?" kind of moments that don't make a lot of sense when you really think about them. Some of the characters don't act at all realistically. You need to turn off your brain and just accept the premise a little bit or you can easily nit-pick it to death.
Paul Rudd and Michael Douglas are both very good. Rudd got buff for this, the same way Chris Prat did for Guardians, but he does a great job of conveying the uncertainty of a guy thrust into a hero role almost against his will. Of course, he is also really funny and his supporting cast are also amusing, especially Michael Pena. Michael Douglas is the heart of the story and the script does a great job of explaining a lot of his motivations. The villain, Darren Cross played by Corey Stoll, is pretty mediocre. Other than Loki and Ultron, Marvel has not had particuarly compelling villains in its movies. Lastly, Evangeline Lilly is just ok in this film, though it isn't all her fault. She is wearing a really distracting wig the whole time. I think they borrowed the wig that Cate Blachett wore in Indiana Jones 4 and it just looks awful.
I had fun watching the movie and it does a good job setting up what Ant Man can be for the Marvel universe going forward. They do a really nice job of fitting it into the existing Marvel universe and Ant Man does interact with important other Marvel characters and organizations. There are none of the lingering questions like "Where is Iron Man?" that sorta dogged Captain America:Winter Soldier.
Be sure to stick around for a mid-credit bonus scene that is pretty dull (and makes no sense when you think about the character's motivations earlier in the movie) and a post-credit scene that is really cool and points toward some big things coming down the road.
