YMMV: Loonatics Unleashed
- Audience-Alienating Premise: Even if you enjoy the show, you have to admit the idea behind it's a strange-sounding one.
- Broken Base: The show had many detractors when it was still airing, bemoaning it as awful. But nowadays you can find a lot of devoted fans for the show who saw it as kids.
- Designated Hero: Ace is supposed to be the greatest hero of all time, but has some questionable moments, especially in the second season. In "Secrets of the Guardian Strike Sword" he calls out his rival for attacking him from behind, then later in the same fight takes advantage of said rival's distraction to attack him from behind. Worse, that same fight is supposed to be proof that Ace is the one who's really worthy of owning his Cool Sword. In "It Came From Outer Space," he refuses to entertain any notion of giving in to Melvin's demand to hand Lexi over. Even though she did blow up his star base, and Tech tells Ace they're hopelessly outgunned and trying to fight would be suicidal, Ace insists on fighting anyway. He even gets mad at Duck for suggesting that Lexi sacrificing herself to save the entire planet is the right thing to do. Before they found out Melvin was lying and had no intention of backing off once he had what he wanted. And Melvin wasn't even going to kill or torture Lexi, he just wanted someone who'd play board games with him.
- Ensemble Darkhorse: Rev and Tech, if only because they're the only characters with somewhat developed personalities and actually have believable and likeable interactions.
- Also Rev's family (who showed up in Episode 18: Family Business) got a MASSIVE fan base because of their quirky natures.
- Evil Is Sexy: Optimatus.
- Genius Bonus: At one point, Duck calls a saber-toothed tiger "Smiley." While this might at first seem to be a jab at the... well, "Saber Teeth," the actual name for a saber-toothed tiger is "Smilodon." That's pronounced "Smile-oh-dawn," for reference.
- Ho Yay: Some fans read a degree of UST into Tech and Rev's friendship. In the second season, the creators may have picked up on this and, in an attempt to reduce it, had Tech and Rev show more animosity towards each other. However, this just made them look like a bickering old married couple.
Rev: If you weren't a coyote - and a guy - I'd kiss you!
- The episode "Family Business" is a goldmine for this with a lot of Does This Remind You of Anything? moments. Rev's parents react to Tech as a stereotypical parent would react to their child's boyfriend, with not trusting him and with sarcastic insults.
Tech: Then lucky for me, I'm both.
Ace: (about Rev) I WAS going to save you next.
- In "Weathering Heights", during the fight against Weather Vane, Tech saves Rev and the following exchange happens:
Tech: I got impatient. (winks at Rev)
- For some reason Rev always gets close to Tech at certain moments, places his hand on his shoulder and stays that way. No reason is given, he just does that sometimes.
- Jerkass Woobie: Danger Duck. You can't help but to feel sorry for the crap he goes through, even if he did a Jerkass move beforehand.
- Launcher of a Thousand Ships: Tech
- Love It or Hate It: The series is, shall we say, polarizing. Possibly what occurs when executives at Warner Bros. , after witnessing the financial bombing of Looney Tunes: Back in Action, decided to copy that "Anime" thing they'd heard so much about and make something the kids of today "understood". The original trailer didn't go over so well. When the harsher designs and dark setting hit the mainstream, Looney Tunes fans around the world revolted, complaining about what they saw as a crass attempt to appeal to its demographic and utter disrespect for its source material. Some say that Loonatics could have been more well received if it was not for Warner Bros' advertising campaign, which claimed that Loonatics was a newer, better version of the original Looney Tunes. Warner Bros. greatly revised the show from its pilot, especially when the news media got wind of an internet petition against the show started by an actual 11-year old boy. The result led to the character designs being softened and the concept altered ever so slightly.
- Moe: Lexi, in her flashback from before she became a hero.
- Snark Bait: You thought Space Jam was the most ridiculed thing to ever be associated with Looney Tunes? Think again!
- Superlative Dubbing: The Mexican Spanish dub deserves a special mention: Traditionally, Warner Bros. tends to dub almost all their animated, non-Looney Tunes-related series from the 90s to this date into Latin American Spanish in Venezuela since it's cheaper to dub there than in Mexico. This seriesnote is one the few modern animated ones dubbed by Mexican voice actors, rather than Venezuelan ones, even if Warner Bros. could invoked the fact the Loonatics are descendants of the original Looney Tunes just to avoid dubbing the series in Mexico. The reason for not dubbing the series in Venezuela could be the criticism the company received from Spanish-speaking fans about how the original Looney Tunes were dubbed by Venezuelans in both Tiny Toon Adventures and some few modern shorts.
- Tainted by the Preview: It wasn't tainted! It was EXTREEEEEEEEME!
- They Changed It, Now It Sucks: The change of the opening theme in season 2 wasn't well received.
- They Wasted a Perfectly Good Plot: People who thing the show is okay without nesserily being awful have said that it's actually a decent action-adventure show. The only problem being... the Looney Tunes.
- This Is Your Premise on Drugs: The reaction many unsuspecting viewers have upon randomly stumbling into an episode for the first time.
- Took the Bad Film Seriously: As shallow as the writing often was, the voice acting is arguably one of the few saving graces of the series.
- We're Still Relevant, Dammit: By all accounts one of the most conspicuous examples.
- Win Back the Crowd: After the failure of Looney Tunes: Back in Action, which starred the classic versions of the characters, Warner Bros. attempted this with a hipper, more modern take in an effort to connect with a younger crowd. Said crowd was offended.
