Good Fun. Based in SF and not New York is always a great change. This film is short but doesn't seem like it. It is clear, introduces characters from comic canon, brings back Janet, drops a hint as to how Scott Lang can go find Tony Stark to fulfill Dr. Strange knowing that Stark had to live to fix things later. Worth seeing if you enjoy Paul Rudd or Evangaline Lilly, or if you are following the MCU, or if you need help reclaiming some "Hope" for Avengers 4. Look up Kyle Hill's youtube Because Science video on why Ant-Man might be the most powerful hero which includes explaining Quantum Mechanics. Quantum Tunneling and World Lines along with "Time Vortex" are important. Worth seeing at least twice pay close attention to the comic book canon references and the Quantum information as it relates to traveling.
