Iron Man 2
The second Iron Man is easily the least memorable entry in the Robert Downey Jr. trilogy. Sure, it introduces Scarlett Johansson as Black Widow and brings in Don Cheadle to take on the role of War Machine, but in the grand scheme of the MCU it’s not all that impactful. Downey remains captivating as tortured genius Tony Stark, though. The MCU was still finding its footing as an interconnected web of heroes and villains in this era, and it would reach greater heights with Stark in the future. But this sequel is mostly just a serviceable follow-up to the film that started the whole thing. — Kenneth Shepard
