Sorry, but its really the whole series. Before i continue, id like to add that many would call me a FFanboy, although i wouldnt myself, since ive never really come to terms with the term. ( geeh, that sounded wierd.)
Nevertheless, all characters in the FF series are stereotypes, dialogue have always been so-so, and well, i truly believe the FF7 popularity came from the fact that it was the first 3d rpg that the masses noticed, and during a crucial era of the console timeline as well. Sure, semoi-steampunk is easy to like, sephiroth is a pretty boy (just as cloud and vince), theyve put some effort into animations as well and that always draws a crowd.
I would also like to add that whoever finds the FF7 story complex or refined or something really should turn of their tv (for, oh lets say, 5 weeks?!) and read a bloody book for once ! its all there, no mystery, just play the game and you shall be answered... And yes, that goes for the ENTIRE FINAL FANTASY series ! its like reading a nice comic, except you get to move stuff around and from time to time affect stuff. If people want "Story" from a game, there just trying to milk their dog to get coffe cream ! Story comes(/came) from guys like Dostojevskij, not people who make their living aided by special effects ...
ended up close to FF bashing here, but i like the series (a lot). Incidentally , i like both comics and novels as well.And i think FF5 was the best (due to game system). sorry for walling, wherever you are, and good night.
