In the original airing of the show the order of episodes was "random", that's why when it comes to the episodes list, you'll probably find threads such as "Chronological Order - Broadcast Order" and even 2009 Re-airing order as well as DVD. Now for this randomness, it maintains certain coherence, as most of the show is mostly episodic, even for the two-episodes mini-story. However if you watch 2006 Broadcast order you'll miss some references here and there, but nothing that spoils the development, and serves for a different experience. Even with that said, I would not recommend start with Adventures of Asahina Mikuru, it doesn't make any sense as episode 1 and made me drop the series once.
The story revolves around Haruhi and company in high school where they start a little club with mysterious purposes, not going to spoil anything. The animation is bright and cute, there are some CGI scenes, at least they looked like that to me, the backgrounds specially the streets in the sunset are beautiful. I have no complains for the soundtrack, Aya Hirano did a great job as voice actress, as well as the rest of the cast. The characters are really special for me, the most the supporting ones, each one comes from a different background that at the same time unites them in that time and space as if it was their destiny, but maybe not...
This series is not to be taken so seriously being honest, I'm not saying this is bad, I gave it a 9/10, it's great entertainment, you can love it or hate, and is surely a show that still years after maintains its fanbase and will hear about it for years to come.
