The thing that all the episodes have in common is this: they are all very well animated. Other than that, the quality of these short episodes ranges from very good, to ok, to really bad. Here' a quick summary of each episode with ratings:
1- Sonnie's Edge (7/10): Interesting world building, cool twist, great use of gore, avarege dialoge.
2- Three Robots (3/10): Good animation, really bad jokes.
3- The witness (7/10): great visual style, great concept and ending.
4- Suits (4/7): amounts to 17 minutes of farmers fighting an army of monsters and gets boring really fast.
5- Sucker of Souls (2/10): good animation, but some of the worst written dialogo I've ever heard. Yet another army of monsters.
6- When the Yogurt Took Over (6/10): Refreshingly short and to the point in its satire.
7-Beyond the Aquila Rift (8/10): Great concept and ending, good looking photorealistic animation.
8- Good Hunting (8/10): Great animation. It takes its time with the story.
9- The Dump (6/10): Simple story, good animation. It can be a little too gross at times.
10- Shape Shifters (6/10): Interestig world building and concept.
11- Helping Hand (5/10): It's just Gravity, but wih more gore.
12- Fish Night (4/10): Surprisingly unengaging. Things happen, a character acts crazy for no reason and then it just sort of stops.
13- Lucky 13 (7/10): Good, engaging story. Yet another alien army.
14- Zima Blue (10/10): By far the best of them all. Good story, great art style and an actual amotional payoff.
15- Blindspot (3/10): non-stop action that gets very boring very quickly. Annoying characters. Cop-out ending.
16- Ice Age (6/10): The live-action is a welcome change of pace. The concept is intereating, if not every original (Simpsons did it). The ending feels way to abrubt.
17- Alternate Histories (5/10): Its concept get old pretty fast and the jokes obly really made chuckle a little.
16- The Secret War (5/10): At first I thought this one was going to be special. It look atmospheric, it took its time to create suspense and develope the story. Then it was just another giant army of monsters with a ridiculously abrubts ending.
Over all, a mixed bag. Good animation, poor writing, Zime Blue was awesome, too many monster armies.
