There is A Love to Kill, Will it Snow at Christmas?, Sorry I Love You, Bad Guy, Cruel City...
Missing you was kind of heavy, but not really in my taste. Padam Padam is also interesting, but its not for everyone. Que Sera Sera is perfect if you want an original plot and very interesting story and characters (but its year 2007). Then there is Robber (year 2008), that one is pretty good. Giant is also interesting - it follows the main characters through the years - but its not really a melo, i think. Thorn Birds is the definition of heavy melodrama :D
And as akin15 just wrote - Secrets is also perfect.
From new things... Firstborn looks really interesting and there is also Golden Empire (which i did not see yet).
