While "The Irishman" has been praised by many, I found it disappointing in its execution. Despite the legendary director Martin Scorsese at its helm, it felt overly meandering and painfully long, frequently falling into tedium. The pacing was a considerable problem; at three and a half hours, it would have benefitted from tighter editing.

The film tried to weave a complex narrative tapestry, but failed to engage on an emotional level. The audience was left unattached to the characters, who were sketched with broad strokes but lacked the depth and nuance required to genuinely empathize with them. Despite the stellar cast, the performances were unable to bridge the gap between viewer and character, leaving an emotional void that could not be filled.

Furthermore, the lack of a central conflict was a major flaw in the plot. A well-defined conflict is the backbone of any film, driving the narrative and characters forward. However, "The Irishman" was largely devoid of such, leading to a narrative that felt aimless and diluted. Instead of presenting a sharp, compelling story, it meandered through time and space, becoming a tiresome journey without a clear destination.

The use of de-aging technology was another factor that detracted from the film's overall quality. While intended to aid in telling a story spanning decades, it was implemented in such a manner that it became a distraction rather than an asset. The CGI applied to De Niro, Pacino, and Pesci was unmistakably artificial, often giving their faces a waxen, almost uncanny valley-like appearance. This was especially noticeable in the scenes requiring physical exertion where De Niro's age was apparent despite the digital facelift.

Ultimately, the heavy reliance on de-aging technology ended up being more of a hindrance than a help, leading to a film that felt less authentic and more artificial - another layer of distraction in an already underwhelming cinematic experience.

In conclusion, "The Irishman" was a disappointment, lacking the emotional resonance, compelling conflict, and narrative urgency one would expect from a Scorsese film. Despite the big names involved, it struggled to retain interest, ultimately resulting in a tedious cinematic experience.
