This movie was REALLY hilarious, especially thanks to Michael Pena, who completely bombarded every scene he was in with humor. Marvel's funniest movie to date after Guardians of the galaxy. It also felt small in scale and scope compared to other superhero movies, fittingly just like the hero it is based on. Ultimately, it is a heist film with a superhero origin story in it, and good one too, which was both refreshing and entertaining.
My favourite thing about this movie was that how it referenced to The Avengers and their stuff and actually felt like being part of marvel's cinematic universe, unlike other standalone films which hardly do it.
The CGI was great. The seamless transition from normal human scale to ant-size scale was beautifully done. And it often made for great perspective scenes.
The movie was overly goofy at times. And I didn't particularly got into it in the first 10-20 mins. Also, the villain was OK.
All in all, a fun, entertaining marvel movie.
