Yeah season 1 is not my favorite. It's kind of slow paced and awkward at times. When I watched them I thought "...yeah, this was good" but then I watched the other seasons and learned how much potential this show really has.
For example, go back and watch "Party of One" from season 1, and then watch "Pinkie Pride" from season 4. There's a *huge* difference in the two episodes. The former is slow-paced, less exciting, and a bit more awkward, but the latter is fast-paced, really exciting and engaging, and overall more enjoyable.
