Sound is painful, but the graphics make up for it.
Lambi 1 is a cute cartoon about people in a bomberman-esque world.
The graphics are easily the best part of the animation, being very unique and really grabs your attention. The graphics complement the style of the animation, going for that cute innocent look rather than the overdone "badass" look. The unique direction the creator went with style certainly makes it stand out.
If it had a downfall, it'd definately be sound. Being out of sync and almost painful to listen to, it's the only reason I could see for someone to not like it. Although it may seem a little slowpaced, that contributes more to the style and makes Lambi 1 feel unique.
In the end, Lambi 1 isn't amazing by far, but interesting enough to arouse your interest to watch the superior later installments into the series.
