Should I watch it?

My friend is trying to get me to watch it and wont shut the fuck up, should i give up and watch it or is it shit?
What do you guys think of it?

yep... but if you don't have read the manga(offcourse this is a dumb affirmation) but first watch the first season and later root:A and maybe the ovas but there is only one... called jack or joker i don't remember

are you jumping directly to the sequel?

No, this was just the first picture i found of it

As someone who has not read the Manga I can say season one is p'okay

Read the manga first then watch the first season and skip Root A.

Season 1's pretty ok, leaves out some stuff, switches 2 arcs with eachother but the animation is ok.

Season 2 goes anime original, yet tries to copy the manga events, changing the outcome.
the story is butchered and the animation went to shit.

forgot to say read the manga.

This. Source material tends to be better most of the time. It's okay to stop reading at part 1; :re feels like an unnecessary sequel.

There's two OVAs you imbecile.

Look OP. Root A was trash. Don't watch it unless you're willing to read the manga (which you should) and have--at the very least--watched the first season. Otherwise, ignore your friend.
