I came into .Hack//Sign with mixed reviews and no knowledge of the characters or the plot / setting. I was pretty skeptical because a couple of my really good friends said it was very boring. Then again I had friends that said it was amazing. With that being said, i just had to see for myself.
Right off the bat I need to address one HUGE CON of this anime. The use of flashbacks and how many episodes they used. The large majority of .hack//sign was used having flashbacks. But not even stuff that we haven't seen yet. There was one scene (that was several minutes long) that was played AT LEAST 10 times in the series. Not to mention for a WHOLE episode they did a review of everything that had happened thus far. When you are dealing with an anime that is only 26 episodes long there is no need to do a 20 minute recap of everything that happened in the first 14 episodes! I can understand if you are on episode 150 and want to recap what has happened, because a lot of information can be forgot... but not in 14 episodes.
It is my personal opinion that this anime could have been finished in 12 episodes. There were moments when the anime was boring as all Hell. Where I wanted to just say "screw it" and go to the next anime or skip that episode. There is tons of pointless information that could have been left out or scenes that were just not necessary. But in the end, within a couple episodes it had my attention again.
Now for some Pros. There was many times in the series where I was very into the series. For example the Grunty scene where Su Casa was searching for the purple berries. It was very emotional and kept me on the edge of my seat. I did find myself yelling at the characters from time to time, At how stupid they were or in anticipation of what would happen next.
There were many characters that I connected with. For example Sora. Sora was by far one of the greatest characters on the anime. His use of humor and whatnot was unparalleled.
In the end the anime was good. It had its cons and pros. But evened out the anime was good. even Though it was good, the chances of me watching it again are not too high.
I recommend watching it at least once and come with your own conclusion.
OVERALL: 8 / 10
