What I didn't like about Search : WWW was:

The pace. It was kind of slow at times and they mixted the scenes a bit here and there.

The romance. It was slow at the begining. And they almost seemed like they didn't have chemistry, but that was solved quickly.

The business part. It was nice to see strong female leads, but the office story was confusing and didn't really appeal to me in the end.

Now, for what I liked:

The performances were really good from all the actresses and actors, but especially from the three ladies, who were incredible.

The second leading lady's romance. It was cute and adorable!!

The attitude of the drama.
