Captain America: Brave New World leaves viewers with several lingering questions. This latest MCU installment, while introducing Anthony Mackie's Sam Wilson as Captain America, falls short of expectations, leaving many plot points unresolved and characters underdeveloped.

The Absence of Banner/Hulk: The film directly builds upon The Incredible Hulk, yet Bruce Banner's absence is glaring. His reaction to the events, particularly the gamma-irradiated Samuel Sterns' rise to power, would have been a significant plot point. His established role in monitoring global threats further emphasizes this omission.

The Leader's Limited Scope: Samuel Sterns, aka The Leader, is portrayed as less of a strategic mastermind and more of a man consumed by personal vendetta against President Ross. His actions lack the grand, world-threatening scale expected of such a villain. His surrender and seemingly simplistic final plan raise questions about his supposed brilliance.

Red Hulk's Uninspired Portrayal: The film's Red Hulk deviates significantly from the comic book version. Ross lacks the intelligence and tactical prowess of his comic counterpart, instead mirroring the mindless rage of the original Hulk. This missed opportunity to present a unique Hulk variation is disappointing.

Inconsistent Weapon Effectiveness: Red Hulk's invulnerability to bullets contrasts sharply with his vulnerability to Captain America's vibranium blades. While vibranium's superior properties offer a plausible explanation, the inconsistency remains noticeable.

Bucky's Unexpected Political Career: Bucky Barnes' sudden emergence as a political candidate feels jarring and unexplained, given his past and personality. The transition lacks a logical foundation within the established MCU narrative.

Sidewinder's Unexplained Grudge: Sidewinder's intense personal animosity towards Captain America remains unexplained, leaving a significant plot hole. The film doesn't provide sufficient context for this deep-seated hatred.

Sabra's Inconsequential Role: Ruth Bat-Seraph, the MCU's adaptation of Sabra, feels underutilized. Her character arc lacks depth and purpose, raising questions about the necessity of adapting this specific comic book character, especially given the significant alterations made to her background.

Adamantium's Uncertain Significance: The introduction of adamantium, while setting up future storylines, feels somewhat arbitrary. Its immediate impact on global power dynamics is unclear, and its long-term consequences remain uncertain beyond its connection to Wolverine's eventual arrival.

The Ongoing Absence of the Avengers: The film hints at the need for a new Avengers team, but fails to meaningfully progress towards its formation. The lack of groundwork for a cohesive team, especially given the proximity of Avengers: Doomsday, is a significant concern. The film's climax would have benefited greatly from the inclusion of additional Avengers.

These unresolved questions and underdeveloped aspects leave Captain America: Brave New World feeling incomplete and raise concerns about the overall direction of the MCU's Phase 5.
