Series Super fun
Galavant is... not what you're expecting. At all. It's a medieval fantasy that doesn't just break the fourth wall but proceeds to gleefully tango-shuffle all over it. The characters get into situations specifically to get a laugh and the songs can have several blink-and-you'll-miss-it double entendres.
The plot itself? Moves at a glacial pace. But after starting the second season I'm not so sure that the plot is what's important anyway. Do you want a solid plot or Kylie Minogue demanding a striptease at a gay bar along with Weird Al Yankovic doing a jazz hands Gregorian chant song?
As long as you go into it expecting lots of humor, you'll have a good time.
Series WORTH IT!
A post modern parody on the stereotypical medieval story slash television musical special. Cheesy, but worth it.
Series Hilariously Fun
Galavant is an irreverent, but affectionate, parody of many medieval dramas, to the point of mocking the idea of the heroes dying because "This isn't Game of Thrones".
The Rapid-Fire Comedy is on point with very few falling flat. The music is simultaneously beautiful and hilarious, fitting given that both Alan Menken and "Weird Al" Yankovic were involved in the series (though the latter was mostly as a character rather than making the music).
Yet, despite being primarily a comedy, there's a surprising amount of really wholesome moments. Such as Richard singing "Good Night My Friend" which gets everyone in the castle to stop what they're doing and just hold each other as they listen (including an executioner and a prisoner). Galavant realizing he's a "Jackass in a Can" and committing to pretending to be Sid's squire if that's what the latter wants/needs. Gareth breaking Richard out of prison and getting him to safety. Richard and Galavant's developing friendship (same with Gareth's and Sid's friendship). Even Madalena genuinely thanking Gareth for loving her.
And after bingeing the entire series, I can absolutely understand why Richard is the most popular character of the show. He can be surprisingly competent at being evil, including creating an entire Batman Gambit regarding Galavant (whom he's only met once) off the cuff. But the rest of the time, he's an Adorkable loser who just wants to be loved, either romantically or platonically. Much of his evil in the first season is due to his desperation for Madalena's affection. Yet, when he finds out she's having an affair with the jester, his response is to ask the man to teach him how to be funny (which he thinks is why Madalena likes him). He's even the best case of Nice to the Waiter. While the series mentions having had several generations of Chef's family killed offscreen, he's perfectly cordial with the man, even befriending him. Not to mention being literally the only character in the series to know the jester's name (Steve Mc Kenzie). Not to mention, he had perhaps the most fulfilling character arc in the series, growing from a Not-So-Harmless Villain to a genuinely badass wise king.
