They were written by sitcom writers, the animation was outsourced to Korea, and everyone on staff had credits that included shows like "Family Guy" and "Beavis and Butt-Head". For a project that was supposed to feel like the original theatrical Looney Tunes cartoons, I don't see how that formula could have produced a result that was anything but horrible.
Everybody loves the Looney Tunes, but how many people really understand them? We all know they're funny, but which of us really know why they're funny? Let me put it this way - my mother is a big Looney Tunes fan. She grew up watching the cartoons on TV, and then got a healthy dose of them again while I was watching them as a kid. But the extent of her knowledge of the cartoons is basically the occasional quote of "Hello my baby" and "Kill the wabbit". She has no idea who Chuck Jones or Friz Freleng or Bob McKimson or Tex Avery or Bob Clampett or Frank Tashlin were, and is unable to distinguish between their directorial styles. She doesn't even know the individual shorts' names - her favorite cartoon is "Hillbilly Hare", but she refers to it as "the one with the square dance". Heck, she doesn't even know when the cartoons were made - I asked her once which era of the Looney Tunes she prefers, and she said "I guess the ones from the '60s or '70s, like the Barber of Seville one." ("Rabbit of Seville" was released in 1950.) She loves the Looney Tunes, but she's about the last person I'd want working on any new Looney Tunes projects.
You can be the biggest Looney Tunes fan in the world, but if you're actually making a new cartoon with the classic characters and the only thing you remember about the Looney Tunes was explosions and falling anvils, your cartoon is doomed to failure. It's not enough to just be a casual fan. One must study the classic shorts extensively and know characters like Bugs Bunny and Daffy Duck inside and out before one can work with them. You need to study the timing, the structure, the pacing, all the subtle things that aren't immediately noticeable to the average Saturday morning viewer. Greg Ford and Terry Lennon understood this; Larry Doyle did not. Let's hope this show's staff fares better than he did.
