10 Most Disappointing MCU Moments
2. Black Widow's Death - Avengers: Endgame
Given that Black Widow (Scarlett Johansson) had her own solo movie coming up and was by far the MCU's most prominent female character, it was genuinely surprising to see her killed off in Avengers: Endgame, sacrificing herself in order to obtain the Soul Stone from Vormir.
And while her death scene wasn't bad as such, it certainly was a bit underwhelming for such a major character.
For starters, the whole Vormir sacrifice shtick had been executed far more effectively with Gamora (Zoe Saldana) in Avengers: Infinity War, so this inherently felt like something of a retread.
Then there's the fact that seeing Natasha and Hawkeye fighting each other to try and commit suicide first was a whole lot goofier than the movie was ever prepared to admit.
It's well known that the scene was heavily re-worked during post-production, and the original filmed version actually featured Thanos showing up to try and stop the pair, but all in all, it didn't land with quite the devastating impact the Russos were clearly hoping for.
The fact that Natasha's death was barely lingered on at all - albeit in a densely-packed three-hour movie - only made her demise feel that much more of a perfunctory footnote.
