Derailing Love Interests/Analysis


 * Often a sign of bad writing, as instead of taking the time and effort to demonstrate Bob's good points, develop a believable connection to Alice, and show reasons why Alice would fall in love with Bob, on his own merits, deeply enough that she can't stay with Charlie even if he's done nothing to drive her away, it instead only serves to make Bob look good in comparison to Charlie, making it look like Alice's reason for choosing Bob is that he's better than that jerk Charlie.
