Having completed multiple endings in this game i'm not surprised that someone who didnt like the XIII story didnt like XIII-2, the two stories are pretty co-dependant (XIII-2 is even more heavily based in fabula nova crystalis lore than XIII was). There are multiple plots etc too though, so i'm guessing hes reviewing the canonical ('real') one.
The story is pretty decent though, dense in lore in places, definitely, but still great. But this is probably one of those guys who moaned about the 'convoluted' nature of XIII. My statement still stands, if you read at laest 3 mature level novels a year i'd expect you to 100% understand this games story. Its not rocket science despite being more 'intense' than the average modern rpg tale.
Personally I loved the game, I've played them all & its my all time 4th favourite FF, but then i'm not a 'professional' critic, haha
My advice (for what its worth), play it and form your own opinion.
