I watched the first season and didn't really like it that much either(though I can see the significance of those scenes now). So, I stopped there. Few months down the road, I was incredibly bored and decided to watch season 2 and by the second episode, I was hooked. Ended up watching till the end of season 4 in a week. So yeah, I would say keep going..this is probably the best and the most addictive show out there. Watch through season 2 and if you still don't like it, then bail out.
Let me ask you one thing. Did you like the episode "Grilled" ? If not, then it's not your type of show..because things go darker and darker from there.
