If I were to be as objective as possible, I'm not about to assure you that you'll like the rest of the series if you don't much care for the first season. That being said, I'd never frown on the idea of giving it another shot; I think it's one of the best TV series, and it is great at being suspenseful. To address the question concerning if it gets better or not, I'd say yes, but that's subjective; I know a few people who like the first season the best. Basically, later seasons tend to get even more over-the-top with the suspense, and if that's your thing, I think you'll like it more. Personally, I wouldn't agree with the notion that no series rivals its depth, but it does have vivid characters and a fickle plot.
In short, maybe give it another try, maybe try to change your perspective, but you don't have to force yourself to like it.
