I want to get into this series but have no idea where to start.
Do I skip the animated movies and TV show?
If you mean start in on the whole of the Star Wars franchise there are a couple of ways you can go about it.
1. Chronologically by release date. This means starting with the original trilogy: A New Hope, Empire Strikes Back, and Return of the Jedi. Then you watch the prequel trilogy: The Phantom Menace, Attack of the Clones, and Revenge of the Sith. Then you'd move on to The Clone Wars television series, the Rebels television series. In the middle you'd watch The Force Awakens and then Rogue One, though you could probably finish off all the existing Rebels episodes before moving on to the latest two movies and it wouldn't really make much difference.
2. In-universe chronologically. You watch them by episode number with The Clone Wars between 2 and 3. Rebels after 3. Rogue One after Rebels. Then 4 though 7.
3. Just the movies, with the two chronological options listed above.
There are benefits to each, and downsides. If you watch in release order you get the experience that most people had, though without the long waits. The movie special effects get better as you go along. The downside is the quality of the movies jumps around. You wouldn't have the same takeaway as longtime watchers though because we've had the original trilogy in our heads for a while when we went into the prequel movies so we were going in with one idea of what Star Wars "is" and the prequels didn't match up for a lot of us. You wouldn't necessarily get the same impression if you're watching all the movies within a relative short span of time.
If you start with the prequels you're in one sense getting the bad stuff out of the way first (personal opinion) so that you can end on better movies. The trouble there is that you might get thrown off by the big jumps in the ages of the films because you're going from early 2000s to now to the late 70s-early 80s, and then back to now again. And that's if you're just watching the movies. And you might like the prequels or otherwise think of them as your personal "original" movies. That's not necessarily a bad thing, but I'm just putting that out there.
Whether you want to engage with the television shows or not is really up to you and how much you'd want to invest. The Clone Wars alone has like 100 episodes or something so that's a lot of time for something that you might not care all that much about. I would be pretty interested though in hearing from someone who hasn't seen the movies and decides to do it all by in-universe chronology. I don't know anyone who's done that so hearing about that perspective would be interesting to say the least.
There's also the option to not bother with the prequels. Lots of people consider them the black sheep of the franchise. Personally I think they're important enough if you want to see Rogue One (not necessary, but it gives you some context) and you'd have to see them if you wanted to watch The Clone Wars of course.
Of course you could always start with whatever seems most interesting to you. Personally I'd recommend that you at least start at the "beginning" of a trilogy: The Phantom Menace, A New Hope, or The Force Awakens. You'd be kinda lost otherwise.
