Should Transformers lore be serious or comedic? Or Both?

Simple question, I enjoy the comedic side of it more especially with all those animation errors and hilarious special effects in G1.

I do see quality in the seriousness of BW, but don't like it when it comes to TF:Prime. When TF:Prime tries to be serious it just seems boring considering how I think the characters look too cutey-animeish and it's hard to put serious storylines with such baby-looking characters (oh look at that optimus primey and his shiny flat face!)
