Corrected entry: It seems ridiculous that Raven acts selfish saying Charles never sacrificed to save anyone. Clearly, and I speak for others not just myself, she was there to see him get crippled saving both the whole team as well as the USA and USSR naval vessels in X-Men: First Class.
Corrected entry: In the labs, the Beast is looking at colour LCD monitors, they weren't available in 1992.
Correction: They weren't available in the real world in 1992. This is science fiction though, and there are mutants both in the films and the comics they are based on that are extremely intelligent and innovative. The character Forge for example, who does not appear in the films but may exist offscreen, has the mutant ability to basically invent anything. Beast is also intelligent enough to invent LCD screens a lot sooner than we had them. He did create Cerebro in the early 1960's after all, which is a piece of technology that we in the real world to this day do not possess.
Next to that the first LCD screens came at the end of the 80's though in low quality and small. By 1992 they were very expensive but a lot better. The actual invention of the LCD technology was as far back as the 1960's.
Agreed that the Beast had the smarts to develop LCD screens but the story should be based on reality. For example if the Beast had pulled out an iPhone, it wouldn't fit the narrative, but the Beast would easily be able to construct such a device should he wish to.
Why should the story be based on reality? The movie doesn't take place in the real world. Should the president in the movie be George Bush since that would have reflected reality? The LCD monitors serve a purpose for the scene. While it technically wouldn't have been a mistake for Beast to have in invented one, an iPhone wouldn't serve any purpose for any of the scenes in the movie.
Correction: That's not a movie mistake, it's the character's opinion. It's insensitive, but her point was that they have friends that have died for the mutant cause. She is annoyed that Charles continually will send his team out on dangerous missions while keeping himself out of harms way. Her opinion might harsh but she certainly has a point.
