Way too long and hardly worth the effort. Very much a less interesting tribute version of Goodfellas or Casino, sure it has good production values, with the exception of the de-aging that never looks too convincing. Acting is capable but never noteworthy or memorable and it genuinely feels like it should have been made in the mid to late 90's when De Niro and Pacino were at the top of their game, because there is an undeniable sense of limitation due to their age. The story is far from gripping and poorly paced, it never really raises any intrigue or interest surrounding the disappearance of Hoffa. I personally would recommend Danny De Vito's "Hoffa" starring Jack Nicholson, a far superior film about Jimmy Hoffa and his disappearance. It is understandable as to why this film spent so long in development and struggled to get produced and distributed.
