First off, love the ZBS reference, while I was a bit more a Ruby than a Jack fan, still brought me back. I find the ZBS stuff a little too over the top with the new-age spirituality when I go back to it now, but I enjoyed it immensely back in the day.
Now to the story
A lot of the comment I was writing in my head is already here, so I'll try not to overduplicate, but it just didn't do it for me. The plot was good enough, if a bit predictable. The time-travel mechanism was unclear and inconsistent in its effects -- why was it transporting people and ducks but not brick walls, radio transmitters, and other scenery (and don't say "it only affects living things," as far as physics are concerned those are just more energy and matter in a fancy pattern)? Was it just affecting these two people and a duck -- if so, why on earth, if not why isn't there any sign of anyone else noticing these unusual phenomena? Also, why is there always conveniently a duck handy to illustrate whatever it was supposed to be illustrating?
The characters, though, were where it really fell apart. As someone who has experienced the untimely loss of a significant other, I don't love how often fiction seems to say that anyone who suffers such a loss must be terribly broken decades later. This guy doesn't need a time machine, he needs a good therapist.
Ziggy was even worse. If you have romantic feelings for a friend, sorry, let me go back and emphasize, a
friend, one who you've been friends with for a long period of time, through which you've both been in romantic relationships with other people, it's
your job to say something about it. Giving passive-agrressive hints and acting like a martyr because they're not picking up on it is simply ridiculous, as there's every chance the person has picked up on it but isn't interested and doesn't want to cause a scene by acknowledging your hints and turning you down, or has picked up on it and is interested but doesn't want to make a scene by acknowledging your hints just in case they're misreading them, or they have just so contextualized your relationship as a friendly one as to not pick up on it at all (as outsiders we can see that she digs him, but he's been in an at-least-15-year-long platonic friendship with her).
I guess both characters were too broken -- and too willfully broken, Liam unwilling to get psychiatric help, Ziggy unwilling to speak up about what she actually wanted -- to interest me that much. By the end I was having a hard time following the plot because the characters were just so irritating.
On the whole the production and voice acting were great (although the drunk acting could use some work), and it's always a mix of fun and jealousy to get those con reports.
