The Netflix docuseries "aka Charlie Sheen" is a two-part, roughly three-hour self-portrait that offers a notably raw, messy, and candid look at Charlie Sheen's tumultuous life, addiction struggles, and public breakdowns. Critics describe it as both frustrating and captivating, with Sheen himself as the dominant voice, reflecting on his decades-long struggles and sobriety for eight years. The documentary features interviews with key figures from Sheen's past including Jon Cryer, Chuck Lorre, Denise Richards, Sean Penn, and Heidi Fleiss. Reviews note the following points:

• Sheen presents a quirky yet composed narrative, dividing his life story into themes like "Partying" and "Problems," though the format of short segments makes the portrayal feel somewhat scattered.
• The documentary is long and exhaustive, sometimes feeling like watching a series of train wrecks with Sheen emerging each time.
• Sheen's openness about his addictions, including candid admissions about sexual experiences during his addiction, stands out.
• While some critics find it exhausting and lacking deeper contrition or reflection, others appreciate its honesty and the absence of sugarcoating.
• Jon Cryer and others provide psychological insights behind Sheen's dysfunction, suggesting a pattern of squandering early success and struggling for redemption.
• The film's structure and some filler content can distract, but moments of poignant reflection interspersed with clips of Sheen's and his father's work add depth.
• The project raises questions about whether it contributes to Sheen's healing or inadvertently glorifies his struggles, without clear answers.

Overall, it is described as a raw, reflective but exhausting look at Sheen's stardom and notoriety, with mixed feelings about its effectiveness and impact, though it captures an intimate and often uncomfortable glimpse at Sheen's life.
