A spinoff from the 2014 film, 2017’s Big Hero 6: The Series expands on its characters and circumstances. Called Back in Action, this DVD presents the show’s first seven episodes.

In these, teen genius Hiro Hamada (voiced by Ryan Potter) finds a chip that allows him to recreate robotic pal Baymax (Scott Adsit). In addition, the young prodigy begins college, an experience that adds its challenges.

With Baymax back in tow, Hiro’s pals push to reunite “Big Hero 6”, their superhero organization. We follow their adventures.

As I watched the pilot episode, I feared Action would offer a forgettable collection of shows. Though “Baymax Returns” didn’t remake the movie, it failed to offer a lot of cleverness or ingenuity, so it seemed like an iffy launch.

Happily, the series gets into a groove pretty quickly after that. Sure, Hero comes with a “villain of the week” construct that can seem predictable, but it explores these new characters with such a fun abandon that it works.

Much of the film’s cast returns here, though some exceptions occur. Most notably, we lose TJ Miller as Fred and Damon Wayans as Wasabi.

All the other primary performers come back, though, and that helps give the series extra oomph. The series adds solid support via a mix of new actors, too, so people like Jenifer Lewis, Andy Richter, Kerri Kennery and Diedrich Bader throw out good performances. Heck, even Stan Lee pops up for a brief bit.

How can I dislike a series with a character whose mother named him “Felony Carl” at birth? It starts slowly but Big Hero 6 becomes a fun collection of shows.

Big Hero 6: Back in Action appears in an aspect ratio of approximately 1.78:1 on this single-sided, double-layered DVD; the image has been enhanced for 16X9 televisions. With more than three hours of content packed onto one DVD, compression became an issue.

This impacted most aspects of the image, with sharpness as one of the problematic domain. At best, the shows offered decent delineation, but the episodes never seemed especially well-defined, and they could come across as a bit mushy at times.

Minor signs of jagged edges and moiré effects materialized, and I noticed moderate edge haloes throughout the disc. Other than a lot of artifacts, no signs of source flaws appeared.

Despite the series’ bright palette, hues seemed mediocre. All those artifacts damaged the colors and made them less vibrant than they could be.

Blacks looked reasonably dark and dense, while shadows seemed acceptable, though again, those artifacts mucked up the presentation. This wasn’t a bad image but even for SD-DVD, it seemed lackluster.

I thought the Dolby Digital 2.0 soundtrack of Back in Action opened up the material in a moderate manner, as the forward channels brought out the majority of the material and became the focal point. Music presented strong stereo imaging, while effects cropped up in logical spots and blended well.

The surrounds threw in occasional elements, but they didn’t do a whole lot. Action scenes gave us a smattering of involving components and periodically brought the material to life. However, much of the movie emphasized the forward channels and didn’t create a particularly involving mix.

Audio quality always satisfied. Speech was warm and natural, without edginess or other issues.

Music sounded lively and full, while effects displayed good definition. Those elements seemed accurate and dynamic. The soundtrack merited a “B-”.

Six Bonus Shorts fill a total of 10 minutes, 42 seconds, as each one shows interaction between Baymax and particular humans. They’re mildly entertaining and not much more.

The disc opens with an ad for Ralph Breaks the Internet.

After a lackluster pilot episode, Big Hero 6: The Series quickly settles into a groove. It brings us a good mix of action and (mostly) comedy to become satisfying. The DVD brings generally positive audio along with flawed visuals and minor supplements. The quality of the DVD disappoints but the programs entertain.
