Critic Reviews for Infinity Train Book Four - Duet

All Critics (6) | Top Critics (2)

Season 4 is... nifty! It's a solid season of television, disappointing only in the context of the expansive terror that immediately preceded it.

Apr 16, 2021 | Full Review…

It's a bittersweet ending but deeply funny, with an imaginative set of new train denizens.

Apr 15, 2021 | Full Review…

Book Four's execution is, as one might expect based on previous seasons of Infinity Train, still pretty top notch. Murashige and Young do a great job of communicating just how frustrated their characters are without ever making them too unlikeable.

Apr 15, 2021 | Full Review…

Compared to the imagination of previous seasons to the point of high-octane nightmares, Book Four is more subdued. This season was not intended to be a finale season and feels more at place if it was in the middle.

Apr 15, 2021 | Rating: 8/10 | Full Review…

It's a shame that this will be a farewell as Book Four is where the creative team behind it seems to have really hit their stride while also being able to take big swings. Not all of them land, but when they do, well, there's nothing quite like it.

Apr 14, 2021 | Rating: 3.5/5 | Full Review…

The result is the show's most emotional season, and also its most heartwarming. Duet speaks to the ethos at the core of Infinity Train: that we all have a chance to do better and get better.

    This show has so much heart and I'm devastated that this is the last season! Watch from the beginning. You won't be disappointed.

    mostly amazing! felt a bit rushed compared to the other seasons, but that's understandable considering whats happening to the producers irl, the characterization was otherwise good
  • Apr 27, 2021
    Infinity Train has one of the best stories going right now, and to see it not be completed is not right.
  • Apr 25, 2021
    Literally Must See Such a good season. Storytelling and writing is brilliant.
  • Apr 25, 2021
    This season was such a relief and light-hearted. A good difference from the last season, I'm glad this show can have so many different themes. I hope we get more, there was a lot of lore happening that I need answers too! Also, I relate a lot to Min-Gi, him and Ryan are amazingly written characters, I loved watching their friendship unfold this season!

    Literally life changing, must see
  • Apr 25, 2021
    A little different than the previous books but still amazing nonetheless. Hopefully, it will get continued.
  • Apr 24, 2021
    Another Brilliant season of Infinity Train, hopefully more will be made in the future.
  • Apr 24, 2021
    This season was such a disappointmen. The show had been getting darker and the character arcs more emotionally complex season after season. This season brought absolutely nothing new to the table. It's kind of just a diet rehash of book 1. I've already seen book 1.
  • Apr 23, 2021
    In context to how the story is meant to be told, this is a great season. It's made as a response to the previous season which was extraordinarily intense. Unfortunately, it is the finale, but it's not the intended finale, so reviewing this in the context that it was supposed to be a mid-series break between the intensity of Book 3, and a prelude to Book 5, this is an amazing season. I hope that HBOmax and Cartoon Network Studios will renew this show for the next 4 Books, as it will only truly be its best self when the entire story is told.
