I have season 1 but...

First things first, did you watch Chapters 1-21 of the 2D Clone Wars cartoon? That sets up a bit of groundwork like introducing Ventress and Grevious, not to mention Anakin's transition to Jedi Knight. As for the 3D series, the order is very jumbled before the second half of Season 3. Basically, the official chronological order goes...

Season 2 Ep 16
Season 1 Ep 16
The Clone Wars feature (not included on any of the season releases)
Season 3 Ep 1
Season 3 Ep 3
Season 1 Eps 1-5
Season 3 Ep 2
Season 1 Eps 6-15
Season 1 Eps 17-21

Season 2 Eps 1-3
Season 2 Eps 17-19
Season 2 Eps 4-14
Season 2 Eps 20-22

Season 3 Eps 5-7
Season 3 Ep 4
Season 3 Ep 8
Season 1 Ep 22
Season 3 Eps 9-11
Season 2 Ep 15

Really, as crazy as that looks, that is the proper chronological order for Seasons 1-2 and the first half of 3. Luckily once you're at the second half of Season 3,, from Ep 12 onward, things are finally in order. An ep of Season 5 was aired out of order, but the DVD/Blu-Ray release has that specific one properly placed so there's no issue there. Make sure to watch the 13 "Lost Episodes" after Season 5, which many think of as Clone Wars Season 6, then I suggest finishing up with Chapters 22-25 of the 2D cartoon.

While it is preferable to watch it in the right order, you can enjoy it in production order as well. You just get some odd moments when you realize you are watching a prequel to a previous episode. I didn't know about the different order when I first saw the show, and I definitely had those odd moments, but I still enjoyed the show.

It would be kind of hard to get watch the proper order with just season 1, as you can see with the previous post, but just go for it and enjoy. Besides, after watching it in production order, it is kind of fun to go back and watch it in chronological order.

I fixed a placing issue for Season 3's second episode as its central plot works as a direct sequal to Season 1 Ep 5, dunno how the chronological order missed that but oh well. Yeah if your wish is to follow Clone Wars chronologically, you should have at least Seasons 1-3 and the feature. Season 2 Ep 16 and Season 1 Ep 16 don't work too well as pilot material or an introductory story, not like the feature does, but they do lead toward that.

Superman & The [Red-Blue] Blur = The Man of Steel

I watched the show in chronological order, which probably isn't absolutely necessary, but I would recommend it. Star Wars.com has the entire series in order here: http://www.starwars.com/news/star-wars-the-clone-wars-chronological-episodeorder?repeat=w3tc

It's interesting to see the viewing order there... As someone who's not got around to buying/watching beyond the film and season 1 yet, I wanted to ask a couple of questions...

I'm a big Star Wars fan, but knowing these got canned mid way through season 6, I wanted to know from fans how good the closure is? Do the stories wrap up reasonably with 'The Lost Missions'? Does Ahsoka's story have a conclusion or is it left hanging?

As someone thoroughly disappointed in TFA, I want to finally get round to watching these true Star Wars stories (looking at buying the box set/s and Lost Missions in the next month or so), but it'll be so frustrating to watch them all and be left hanging. How do fans feel about the ending? I just want to know whether to expect them to suddenly 'end', or whether things feel finished (even if imperfectly)?

I'll be buying and watching them even if things aren't ended properly, but if I know one way or the other, at least I won't be screaming "Nooooooooooo!" ;-)

Damn, this show is out of order too? Why is Star Wars always doing this making it hard on us. Almost halfway through season 1 though... What should I do? Never seen past this In the series.
