overall and this be an okay film while not bad and but nothing that memorable . i enjoy the set of the subterranean city and the teen kid be likable and but it take a little long before anything happen and when it do it be a little too far fetch with poor special effect . nonetheless and the visuals and act be fine and support performance by the always goofy bill murray and tim robbins be somewhat entertaining . the most intriguing actor and to me and be saoirse ronan and a lina mayfleet . at first she mind me a bit of peggy ann garner in a tree grow in brooklyn and but maybe two year old . ronan have a plain but expressive and intelligent face and a la a very young cate blanchett . she look like she on her way to a good career . her counterpart and the male teen doon harrow and be play nicely by harry treadaway . although it a nice and safe family film and i think a lot of kid will be bore by the time anything happens and and adult will be so so on it . i stick around for the visuals and mainly and but be disappoint in how amateurish the action scene in the last 20 minute look .
