Dear God.... This was a struggle to watch. I don't get why people liked it so much.
The 3D is uncanny, especially with the janky motion capture. The models are primitive, and the lighting is unnatural. Overall, it's just really creepy to look at.
And I would try my best to forgive that, if it weren't for the awful writing. The plot of this season is worse than a rough draft-it jumps between plot points without giving the audience any reason to care about what's going, and all the characters get all excited with their overexaggerated voice acting as if the audience is expected to feel the same way. It's all just...bleurgh.
I just couldn't stop cringing the whole time. It feels like this show should be a kids' show-the story is so empty and so stupid that the "adult" references stick out like a sore thumb. I can't speak for the later seasons, whose animation is leaps and bounds better, but I absolutely have my doubts about whether this story improves at all. It is NOT fun to watch, at all.
The rotten cherry on top is the fact that all the episodes got shoehorned into this movie format that makes them feel even clunkier to watch, with no clear transitions to make the lacking plot any easier to understand. Thank God their later series, like Murder Drones and The Amazing Digital Circus, are MILES better, both in terms of animation and writing/story.
