These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
In "Double Date," was Lola really stupid/crazy enough to fall for the lines she'd just fed Daffy, or was it all a Batman Gambit to get Bugs to call himself her boyfriend? Or both?
Base Breaker: "Casa de Calma." Some fans liked it for how it harkens back to classic Looney Tunes formulas, but at the same time, it was hated by other fans for that reason as well.
Broken Base: Lola Bunny has been a Base Breaker since she was introduced in Space Jam. Her incarnation here is seen by her original detractors as being a great improvement, while others who grew up with and liked her from her introduction fifteen years earlier generally see her original self as superior.
This whole show is one between those who hate it because it is nowhere near as good as the original shorts or Tiny Toon Adventures, and those that love it for the different direction it is taking from the older cartoons.
Cargo Ship: Apparently between Elmer Fudd and grilled cheese.
In "Members Only", Lola misperceives Bugs to be a bad boy after a failed attempt to get Lola to break up with him. In "Rebel Without A Glove", Bugs really does become a bad boy by way of leather gloves.
Ho Yay: You could easily say the premise is that Bugs and Daffy are married, and nothing would change at all. It doesn't help that in the first episode they're on an Expy of The Newlywed Game. And of course their opponents, the Goofy Gophers, have long been an embodiment of Ambiguously Gay.
After 'Double Date,' we should just make a separate page for this. Here's the short and long of it: Daffy wins an romantic evening for two, so who is the first person he asks? Bugs. If that wasn't enough, when Bugs clarifies that a 'romantic evening' means a date, Daffy turns and asks Porky to a date. The kicker is when Porky accepts. And waits outside his house. With flowers. Even the SONG from that episode, 'Be Polite,' had gratuitous amounts of Ho Yay, but that's to be expected when you're dealing with Mac and Tosh.
With respect to the two latter, the song "You like/I like" takes things even further.
Jerkass Woobie: Daffy, in earlier episodes. The writers weren't sure if we should hate him or pity him.
Love It or Hate It: The series is lauded as an amazing show or a slap in the face to the classic Warner Brothers shorts and characters and a sign that Cartoon Network can't create a good animated series anymore (most purist fans will rally behind the second camp).
It's possible to love both, of course, but their comedic styles are very, very different. Almost like comparing Seinfeld to the The Marx Brothers.
Moral Event Horizon: Daffy may not be a villain, but he crossed the line in "The Float" when he tricked Porky into giving him all his life savings, leaving him broke.
Its even worse since he exploited Porky's good nature, saying he needed a kidney transplant just to get the money-370,000 dollars. Simply for a yacht. Not only did he con Porky out of his life savings, he emptied his debit account and pawned off a priceless watch that Porky's grandfather gave him. And he doesn't bat an eyelash. At this point its plainly clear that Daffy's a Villain Protagonist.
Cecil crosses this in "The Shell Game" when he plans to shoot Bugs and Porky in order to keep them from exposing his scam. It's not even played for laughs. Not even Yosemite Sam or Elmer Fudd in this incarnation or any other would go this far.
He also seems to be a caricature of people with mental problems, something many viewers find to be Dude, Not Funny!.
Made even worse because in earlier episodes he was actually funny, (kinda) sympathetic, and was implied to be going through some major Character Development ("That's My Baby" and "Beauty School" were hugePet the Dog moments). Then came the aforementioned Moral Event Horizon in "The Float" and all hope was lost. And he's getting worse, to the point where he's arguably an Anti-Sue now.
Lola's starting to become this to some who think her blatant stupidity and stalker tendencies are less endearing now. And she, like Daffy, caused Porky to fail his Driver's Test twice.
Bugs is this to a few viewers, for having a vastly different persona than what we're used to (a Straight Man instead of a Karmic Trickster), and the fact that most other characters are Straw Losers to him.
Cecil from "Customer Service". He has no redeeming qualities and purely exists to bother people like Bugs by randomly cutting out their cable. While this seems small, the smug way he goes about it and his Jerkass attitude tend to push him into this way for most viewers.
The guy reaches a new low in "The Shell Game". Not only does he extort Bugs by faking an injury, but it's also revealed that he's been doing the same to others countless of times. When Bugs finds out he's also extorting Porky and the two of them try to expose him, he plans to shoot them in order to keep them quiet.
Seasonal Rot: The 2nd half of the first season isn't considered as good as the 1st, a rare case of this happening within a season. "The Float", which aired in the second half, is considered the low point of the series so far.
Take That, Scrappy!: Lola's treatment in-show is possibly this, as her original debut was reviled by many fans.
They Changed It, Now It Sucks: Online fans of the classic shorts and 90's revivals were skeptical about this update. Then they saw the leaked images, and they were not pleased. This also happened months before the show premiered. Cartoon Brew is a classic case—it covered the show in several blog posts, each receiving 200-plus replies!
The news that Joe Alaskey wouldn't be returning to voice Bugs Bunny (or indeed, anyone) got this reaction. It would probably have been a lot worse if not for the fact that they brought back Alaskey's predecessor, Jeff Bergman to pick up the role — although Alaskey is near-unanimously regarded as the better voice artist, Bergman still has plenty of fans.
Tough Act to Follow: The show producers intentionally lead this series in a different direction from the original shorts in an attempt to avert being compared to them, similar to how James Cameron shifted the Alien series from horror to action with the second film—this was because the producers had accepted that it was impossible to live up to the original cartoons.
