Exaggerated: All marketing material heavily features Alice, and she quickly becomes extremely important. The audience despises her so much she's hit by a falling plane by the second episode.
Justified: Alice's actress doesn't act very well, so it's hardly a surprise the audience didn't like her.
Alternatively, the audience didn't have a problem with Alice, but she's written out because of problems with the girl that plays her.
When Alice is going to get written off, her brother Jack comes to pick her up. Because of actor chemistry, the audience changes their mind about her.
Double Subverted: After the business with the actress is complete, Alice returns. The audience loathes her due to this, and she quickly takes a new job in another country.
The executives take the wrong message, write off Jack, and bring Alice back for more loathing.
Zig Zagged: Alice is introduced with much fanfare, doesn't gel well, and is going to get written off. Her brother comes to get her and that is well-received. The execs don't understand and bring back Alice with no Jack and it falters, sending Alice for a new job in East Asia. She comes back in three episodes.
