Entertaining enough movie, if a little light on mutants and with any character who isn't Wolverine or Yukio being drawn in pretty much one dimension. Doesn't have a lasting effect on the X-Men timeline (although since DoFP, it's arguable if that's important), but Jackman gives good value for money as usual.
Word of advice for viewers looking to read the inspiration behind the movie: don't bother getting the Amazon exclusive Limited Edition Comic Book version. As the item description says, it's a miniaturised reprint of issue 1 of the 5-issue arc, and is packed into the standard-sized BluRay case (so you can imagine how small it is). The same size as the leaflets you get in BluRay cases, and printed on the same thin paper, it's little more than an insert, and certainly not worth paying 'extra money' for.
My recommendation? Get the regular release BluRay, and use the money you saved to buy the full 144-page story: www.amazon.co.uk/Wolverine-Claremont-Miller-Marvel-Hardcover/dp/0785183833/
