I feel like the year began and ended strongly. Personally I thought Zack Snyder's Justice League was amazing, epic and cathartic and it was nice to see that overall it ended up being the director's best received work. Then the year got a bit bumpy, Black Widow was meh, I REALLY liked The Suicide Squad but audiences didnt care for it, Shang Chi was a pleasant surprise, Venom 2 was....well it was Venom 2 and the Eternals was a complete uninteresting snoozefest and Marvel's first critical failure.
But then, just like he's always bound to do, in the 11th hour Spidey came swinging in to save the day with an absolutely incredible film that knocked my socks off and wasnt expecting it to.
So NWH and ZSJL are the winners of 2021 for me. Both amazing, epic films for totally different reasons.
