the stories take place in different places in EVERY episode, no historical consistency because the action can happen at any chronological time like middle ages or the futur or prehistory, just gags, jokes and less stories, difficulties with canon elements, many episodes where the stories do not follow or do not relate with elements that have happened in the episodes before, we do not even know the city, the region or the country where the adventures takes place

i love Looney Tunes and Merrie Melodies, they have great characters but shitty background, it's just an exemple, a bad exemple i know, anyway the warner shorts aren't makes for having a deep background
