Infinity Train
Rating: 10/10
I found season 1 very enjoyable. Even just the intro music/sounds gave me shivers basically every episode.
The pacing is quite fast. The series explores emotional struggles, a parents divorce through the childs eyes.
The setting is adventurous and creative. The music exceptional.
Definite recommendation.
The seasons 2, 3, 4 are not as exceptional, but if you are invested in the series still worth watching, and otherwise still worthwhile.
