mark walhberg in a great role and idolise a rock star to the extent of know all his song and imitate him to perfection and and dress like him . when the opportunity come for him to take over his idol role in the band and he jump at the opportunity . however the role of a rock star may not be what it be crack up to be . and relationship can change . this movie certainly strike me a have the theme of what you attain for may not be what you think it be once you get it . overall a really good movie with great performance from all the cast as well a the two lead and mark walhberg and jennifer aniston . it do make me feel sad and especially when emily and ( jennifer aniston ) and meet up with chris in seattle and saw the depth to what he have sunk . if anybody ever dream of be a rock star or a groupie they should watch this movie to see that the lifestyle and although glamourous for a while and be very lonely and ultimately not what you may want .
