No, you're not. I rewatched it recently and I found myself loving it again.
I loved the world they created. It's so vibrant and colorful. The city of San Fransokyo has so much character (it's similiar to Blade Runner in that it's a city in the US being a combination of both Western and Eastern cultures) and you can tell there's more to it than what you see from the perspective of the characters.
Speaking of the characters, I loved them. Despite being a bunch of nerds I could still find myself relating to them, especially Hiro. Watching him learn to cope with the death of his brother, battling with raw emotion and eventually honoring his brother by becoming a superhero and saving lives was very powerful.
I can't wait to see where the series will take us next.
