Final Fantasy VII Crisis Core

Ah a game I waited for many years. Sadly.... I regret buying it right away. The game was fun to play but it was so short and easy that... well i beat main story in 8 hours. The last boss died without me taking a hit. The Game was good but they spent like 3+ years on this game and all they could do is make it a few hours long? Really... people say the side quests help it out but really they don't. They are all the same.... the same thing over and over again.... so what you all think of it?
