Write a question about the following article.

I 'll put my review below the cut s you wo n't see spoilers if you do n't want to . It was n't as good a the first one , but I liked it . I was looking forward to it mostly for the Carmen acting story . While I do n't think the poor actresses should be made to play the same characters in four movies , combining three books into one movie made it seem a little rushed .

Question:
What may be the reason why they do n't want to spoil the movie ?
pick from the following.
[1]. Because others will be going to see it .;
[2]. Because they do n't want to lose any fans of their blog .;
[3]. Because a movie has been ruined for them before .;
[4]. None of the above choices .;
