quick question off topic Star wars

I would watch them in the order they were released.

I would recommend the following order, those between () are optional:
4,5,(2,3,)6,7.

Reasoning behind this order:
2 & 3 spoils things that are reveled in 5. With 2 & 3 also helps explain some things that are going on in 6. Holiday special, while officially a part of the series, can easily be skipped, as it's terrible.

I'm pretty sure there are some nice lists that you can find online.
