I can't say for sure whether the MCU is capable of making a comeback, but this was one AMAZING movie!! The humor was through the roof, the plot was simple, precise and to the point without any unnecessary detours and the set design / costumes were immaculate!!
One of the best parts about this movie is the balance between sentimentalism and the R rated nature of it. You get your fair share of tears and laughter.
Please don't bring your children though, it's a R rated movie.
Highly recommend it!
