I'm a well read grad student who's bluntly honest about all things, although I try to be most honest about myself.
I wouldn't suggest starting mid-series at this point: the history simply won't make sense. The original X-Men started with Wolverine and all ended up with Cyclops. Laura, aka X-23, is now involved.
Having said that, I loved the Purifiers. Or I'm horrified by them, but I did enjoy reading their backstory, and seeing them getting their butts handed to them in battle. I love how resourceful these teens, and their teacher, Kitty Pryde, are in this series. I love the banter and the humor.
I just love it all. Moving onto the next volume next, in fact.
