Thing is, its not even the premise. Its the way it was executed. It was, like, two issues after she and Hal broke up that Jordan started indicating the relationship and in the #24 issues of the Green Lantern titles (the Lights Out arc, which was only three issues after she and Hal broke up) that it was first stated that she had "feelings" for him.
So, yeah, its not the premise of the whole thing. It was the fact that it was rushed and was essentially based on bickering/flirting akin to something that you'd see in the most generic office sitcom, except somehow even more ham-fisted.
