People online are saying that Jorge Javier is a breath of fresh air for such a show like GH, but Milá is GH. No one can beat her on that job - NO FREAKIN' ONE. However, let's face it, this guy does pull audience. "Sálvame" already owns about 24hrs of programming in Telecinco (4hrs in daytime Mon-Fri + 4hrs Fri primetime), and he host almost all of them (the days he has a primetime show, usually on Friday's he does not host on daytime, Paz Padilla has been his regular replacement).
However, Mercedes Milá's shoes are just too big for him to fill. Even though he's good at what he does, for me, he's not the right one to replace Milá. He's not cutthroat, he's not as spontaneous, and many more things. His style is not made for GH. Probably Jordi González, who's hosted the past 2 VIP seasons, would've done a much more suitable and likeable job.
