Bridge of Spies was boring. Forrest Gump was lame. Haven’t seen the others. Basically, Tom Hanks isn’t so bad that he shouldn’t be an actor, he’s just not very good. Any competent actor could play his roles. The great actors, Philip Seymour Hoffman, for example, take run-of-the-mill roles and make them really come to life. Tom Hanks never does that, he just turns up, reads his lines in a competent way, and banks his paycheck.
Edit.
Any actor could have played Tom Hank’s role in Saving Private Ryan. The assault on the beach was awesome, the rest of the movie was lame.
The Terminal was boring, lame nonsense.
The Green Mile was absolutely heinous. Utter bilge.
Can’t be bothered going through the rest of his films, but most of them were lame. The ones that didn’t suck could have been played by anyone. Toy Story is a great movie, but it would have been a great movie with anyone else replacing Tom Hanks.
