Jack Aling @ Sundance 2022’s review published on Letterboxd:
Watching Infinity War and Endgame in one sitting felt intimidating mainly due to the almost 6 hour total runtime but it surprisingly flew by and for the first time felt like a truly complete experience. Having the climatic ending of Infinity War be the pivotal moment in the middle rather than the sombre ending made the 'second half' of Endgame feel so triumphant.
We saw the characters that we have spent the past decade with, lose so magnificently that when the now jubilant Avengers theme kicks in for the Endgame title card you can't help but feel empowered and ready for the finales to end all finales.
The end of the line for many of the original six Avengers that started it all, it's a bittersweet end but feels all that more satisfying because of the time that audiences would've invested into this series.
A nostalgic trip down memory lane that brings back everyone and everything great from the MCU which will forever have the experience of the opening night IMAX screening for me embedded throughout - every time I hear 'Portals' I will always feel empowered.
"No amount of money ever bought a second of time" is a hilariously poignant quote from this, the highest-grossing film of all time.
