House of X, along with Giant Size #1 and New X-Men #114, is one of the greatest things to ever happen to the X-books imo. Most characters have been very well served, with many interesting stories and angles coming out of it.
That being said, who would you say has lost out during this era? My answer would be Colossus - between the implied action he took in the X-Force book (though not certain), and just an overall lack of character development, he's been ill served in this era imo. There hasn't been a new or exciting angle with him - he's not vital to the line or the book, it seems.
Beast has also been handled in a way that I'm not crazy about, but I understand this much more, given what was going on with the character before all this.
Any thoughts?
