I think Hanks is great as Forrest but I do think it’s isn’t even that good of an acting job.

Besides the scenes of him crying, I feel like most people could take an acting class, watch Forrest Gump a few times and then be able to do the Gump voice, mannerisms etc, it wouldn’t be the easiest but putting on that voice and having the same facial expression that Hanks had for 90% of the movie wouldn’t be that hard
