I was awestruck watching the way it took off. One character at a time, it kept developing. The fantasy was top-notch, plot like never before. It gave the traditional save-the-world genre, a new look. Season 1 was magnificent. Few characters, mostly Hiro, were impeccable. It did look stretched in the second half. The first 4-5 episodes of season 1 were exceptional. Soon, it started slowing down. Episode 10 was the greatest of them. However, yet again, it started slowing the pace and awesomeness. Only the last couple of them were magnificent after the 10th. The climax was stunning. I enjoyed the complete season 1 and it was a package full of fantasy, emotions, creativity and wonderful characters.
Season 2 never looked the same. It couldn, even for once, keep up to the level of the first.
I eneded in the middle of season 2 until things started making no sense whatsoever. Hiro wasn't hiro either.
