 Person1:      Well , I'm no movie expert , but those special effects were impressive by any standards .  
 Person2:  Special effects ? Baloney ! That movie was made on a shoestring budget . They've been using trick photography like that for years  
 Person1:      Okay . But you have to admit that it was an exciting story , especially with that surprise ending .  
 Person2:  You should read the book . The original story is much better and has a different twist at the end .  
 Person1:      Oh , really ? How does the book end ?  
 Person2:  Read it yourself and find out !
