My general thoughts:
--> The Top 4 finalists: in fairness, lahat sila magaling in their own right. Jason Dy with a powerful balladeer-RNB-falsetto voice. Rence with the classic smooth OPM voice. Alyssa with a mega powerful voice in a 19year old. And Leah with a professionally powerful voice rin. To me, except si Rence, the three were all deserving to win kung boses lang talaga ang labanan.
--> Whoever wins from the Top 4, laging may nega na masasabi. If Rence or Alisah won, people would have shouted that The Voice is being a charitable institution again like what happened when Lyca Gairanod won. Jason Dy, masyadong makulot ang boses. Kung si Leah, biritera na naman.
--> As for Jason Dy: after Kokoi Baldo and Miro Valera left, Jason and Leah were my bets. Personally I'm happy with the results and I think that Jason deserves the title. He may not have very good song choices during the grand finals weekend (and I agree with all of you that his duet with Charice is a bit off, nilamon sya ni Charice) but if you watch all of his performances since the blind auditions, he is a very good package of a total artist: good looks, good voice, good dancing skills, and feet are on the ground.
--> And for sure, the other finalists will hopefully all have a brighter future. Sana hindi sila pakawalan ng music industry. At sana pati yung ibang mahuhusay and really incredible artists such as Tanya, Kokoi, Arnee, Miro, Kai, Bradley, Mackie, Nino, etc may also be given a chance in the industry. Panahon na for new talents, for a new kind of music, for a new set of artists, for more sensible songs.
