Star and Mewni Creek/Tropes/YMMV

Kelly: If I don't come back, tell my folks I left to live a new life.
 * Ass Pull: The show's second episode "Kelly's Story" explains Kelly's existence on this show; she makes a visit to Mewni to for a quick pop-in to see her other friends, a few seconds before the Mewni and Echo Creek were merged! And before she left, she tells her friend Jorby this...
 * Author's Saving Throw: Pony Head taking a level in kindness and losing her Jerkass traits makes her a better character than in the previous show.
 * Base-Breaking Character: Star. Upon the events of Forces of Evil, she's become more arrogant and stubborn, along with becoming more dumber.
 * Broken Base: Mewni Creek ' s shift in genre in becoming a slice-of-Life situation comedy to be reminiscent to the first half of Star vs. the Forces of Evil ' s first season is either good for fans of the first season or just sub-par for fans of the later seasons.
 * Seasonal Rot: The second season is downplayed for the most part, while it had some focus on the secondary characters, it had a few episodes with Star. Fortunately, the third season was able to rectify everything, with having more episodes focused on each character.
 * Tough Act to Follow: This show is So Okay, It's Average than Forces of Evil and its mundane setting is less than pleasing.
 * Why Would Anyone Take Her Back?: One episode has Marco dumping Star for her reckless behavior, yet takes her back after realizing it was a mistake. One would think he did the right thing after her sudden Character Derailment.
 * The Woobie:
 * Tom and Kelly both share the feeling of being cut off from their home and families after the magic had been destroyed. Not to mention how they're struggling with Earth culture.
 * Jerkass Woobie: Star's much more miserable than before. She's cast aside from her fellow Mewman citizens after destroying the magic. And her developed anger issues from the protesting Mewmans really doesn't help much. All she wants is respect for what she does for once.
