I have seen Game Of Thrones and I really love it. I haven't seen Avengers and I really doubt if it will be as interesting as GOT
I'd watch both of them I'll say, These two movies have trending on Netflix since it's release and out in the Cinema. I would prefer to watch the Avengers Endgame first of all.
I have watched so many series of Avengers and really been great if I watch the newly released movie 😌😊.
While for the other movie, GAME OF THRONES (GOT), I've been following up this movie watching Season to Season, now for the newly released, I've watched the first episode which is quite interesting. I'm hoping to watch the second episode and probably the rest of the episodes soon 🙂😁.
These two movie is out for whoever that would love to watch it. Both are really interesting, full of actions. You'd never get bored watching them.
Well...I'd watch then both you know! however I would start with avengers because it's quite shorter, I mean there's just three Avengers movie before the endgame. And as for game of thrones I would need to exercise patience in following the series from the very beginning which would take longer time. Interestingly, if you look at it the other way you could easily just follow the end game by just seeing infinity war but to trully really understand why the phrase " Winter is Coming", you will need to start the game of thrones series from the first season down to the latest.
Besides all of these, I would advice you wacth them both since they are both super cool and fun pack with enough actions and humor.
