The "minimalistic" or "simplistic" style of cartooning has been around for ages (e.g. Powerpuff Girls, Clone Wars (cel animated), Batman, JLA, Teen Titans et al.) -- I don't necessarily think it's weird, just different.

Animated was an unorthodox aesthetic for Transformers being so 'simplified', but then so is the live action movies which are super-complex. The more orthodox style that we're used to with Transformers is more closely related to Japanese mecha. So I'd personally really love to see a new Transformers series animated like this:
