Definitely worth a watch.

Rating: 9/10 (1 January 2012)

OK, so I've seen X-Men: First Class at least a couple of times now and suffice it to say it definitely holds up to repeat viewings. Let's start with the good.
The casting is great, the two leads Erik Lehnsherr (Fassbender) and Charles Xavier (James McAvoy) have great chemistry between them and these are the most important roles in the movie, so you need strong actors for that.
The entire plot revolves around the dynamic between these two characters and it's the better for it.
Erik Lensherr comes from a troubled (German concentration camp) past which results in this sort of bottled rage which is his source of purpose in his older years.
"My anger outweighs my guilt." Heresy! How dare I use a quote from a Batman movie!
But honestly, I think the same applies to Magneto with a big difference of course. He is blind to the fact that he is on the road to becoming what he hates the most. This difference in ideology between Erik and Charles is what causes the conflict between them.
Fassbender certainly proves up to the task and I can honestly say I enjoyed his performance as Magneto more than Sir Ian Mckellan's.
Without saying much, James McAvoy as (Professor) Charles Xavier is equally brilliant. He exudes a calmness and gives off the sense of a man wise beyond his years. I enjoyed his performance and it was also fun seeing X's younger years.
The action/special effects are remarkable, which is to be expected from a (Marvel) comic-book movie. And I liked the music too, in particular, Magneto's theme.
If I had one complaint it's the constant hammering of the idea of feeling out of place. I get why they do it, it just gets annoying after a while.
All in all, if you're a fan of comic books (movies), you should make sure to see this.
If you're not, it's still good entertainment.
9 out of 10.
