6 Most Unforgivable Plot Holes In Comic Book Movies

3. Tony Stark Randomly Gets His Heart Fixed, Despite That Not Being A Thing - Iron Man 3

One of Iron Man's defining attributes is his shrapnel-embedded heart; it's a reminder of the incident that led him to becoming Iron Man, and a long-standing character trait that makes him the complex guy that we know and love. It's also mentioned, oh, eight or nine times throughout the franchise that, should Tony try to remove the shrapnel from his heart, he would outright die: he needs that arc reactor in his chest to survive. But then - out of nowhere - Iron Man 3 throws an illogical curveball the size of the Avengers tower at the audience: Tony is (for some reason) able to remove the shrapnel from his chest via surgery. All of a sudden, it's taken out and he's plainly fine. It's half-heartedly justified by way of a Chinese doctor, but what gives, Marvel Cinematic Universe? Why didn't Tony just do the same thing years and years ago? You know, when the damn thing was actually poisoning him? You might be thinking: well, this isn't a plot hole, but you'd be wrong on that. After all, this one sequence throws the logic-factor of previous Iron Man movies into the air for the sake of a quick fix - the speed of the reveal is way too lazy to enable audiences to buy into it. Fact is, it makes no sense when viewed in context with everything that came before; essentially, we - as the audience - were told one thing, and then this happened, thus negating what we thought we knew about the nature of the very crux of the Iron Man series. It's essentially like being made to care on false pretences.
