Seriously, stick with it. Chapter 6 is easily the worst part of the entire game. Chapter 7 is ridiculously awesome. While it holds to the same basic concept, it varies up the characterization and story enough to be an absolute blast to play through (and it involves another massive nostalgia trip back to Square's golden era). Chapter 8 isn't quite as good, but it's nowhere near as bad as Chapter 6.

I actually took about two months to finish Chapter 6 because I just didn't want to keep going with it. Then I hit Chapter 7 and I suddenly had my second wind and beat the game in a week or so.

Just stick with it. It pays off. At least we didn't get the original version.
