It could be any tv series. You could want a remake because the previous version didn't satisfy you. If they already have a remake, you thought it sucked big time.
For me I say Legend of Lady Chung. I really liked that story, they need to make a new one. The one with Gallen Lo doesn't count as a remake, it's more like a parody. I'm sick and tired of remakes of the "classics" such as Legend of the Condor Heroes and Return of the Condor Heroes. Time to give respect to other series that are good such as this one.
Another one I would just completely redo is Meteor Garden, now that can afford to do more with it with better technology and stuff. The storyline although follows the manga better than Hana Yori Dango-JDrama, is too draggy, takes away from the romance of it. So I would change the story a little, the hair and makeup people got to go to, and the props people need to do better too. I'm sorry if some of you liked the cast, I recast them too. I'm going to use Japanese character's names, you can think of the equivalent on your own, since I liked them better.
Makino Tsukashi.........Ariel Lin
Domyoji Tsukasa......Mike He
Hanazawa Rui..........Figaro Ceng Shao Zong
Nishikado Sojiro.......Gino
Mimasaka Akira........Jacky Chu
I just think these guys are so much cuter and they can act too. This is a type of role I would like to see Ariel in.
