I'm hoping for LOS II too; the first one was very suspenseful and I loved Roger's performance in there, he was terribly frightening to watch! ^.^ WHICH IS GOOD!
But either way; I cannot wait for DIE Again to come out! As said many many many many times prior to my post; in DIE, the first one, the producers actually made an alternate ending (one with Bobby Au Yeung and Power Chan as cameos) due to the high demands of fans (they wanted a happy ending)... So TVB gave them their happy ending; which kind of gave the series a spin, that lead to the sequel... ONE IN WHICH ROGER LIVED! You should probably check it out if you haven't seen the series - the actual series as well as the alternative ending (its funny)!
And since you don't like Sonija so much; you should give the series a try! Sonija's popularity pretty much went up due to her performance in DIE; which I thought she rightfully deserved, since she did a very good job in the series... The improvements were vast, people just need to give her a chance; her heavy efforts really truly shows!
