Every X-Men movie up until First Class was really a Wolverine film in disguise. The main arc of the film always belonged to Logan, and his role as protagonist was never in question. Once the series began to reboot itself with First Class, the tone and direction changed sharply. Gone was the metallic and somewhat darker aesthetic cultivated in the previous films, and in came a fresh and lighter take on the material. Having the backdrop of the sixties helped bolster that mood, making First Class the most fun entry in the franchise. Still, First Class couldn't escape the need for a definitive protagonist, and since it was born out of the ashes of a planned Magneto prequel, it was that character who took on the bulk of the film's arc. This didn't make it bad at all, but it did undermine a bit of the feeling that we were finally going to get the team-family vibe that the other films hadn't focused on.
