Went with 2 kids (12 and 9), husband and self. Only 12 year old did not like it but did not like the whole series. Personally, I love learning how Prof X and Magneto came together and apart, the inner struggles of good and evil, seeing how simple human weaknesses play such a crucial role in the roads we choose, etc., etc., etc.
In a few words, a great summer escape and history for are XMen fans. Don't read into things too deeply, like dialogue holes, etc. Just make this part of summer fun!
