Should I read Luminosity if I disliked Twilight? Does it matter why I dislike Twilight? Can I read it if I never finish Twilight?

(I tried reading Twilight this week. Got halfway through it. The writing style is very workmanlike - good at describing the surroundings, and just enough other important details to move quickly from point A to point B in the plot. Descriptions of Edward are limited to monotonous repetitions of "perfect" and "beautiful", and descriptions of Bella are absent. None of the dialogue is clever. All the boys fall for Bella, who is not interesting; and her reaction (only wants what she can't have) is repellent. The central love story is unconvincing, but is a little interesting because Edward is unpredictable. So far, it is an efficient vehicle for romance-novel cliches. I may finish it, but will feel guilty if I do.)
