According to my experience, whether movies, soaps or TV shows can help depends largely on the language ability of learners. It is highly beneficial to those intermediate level learners or someone with better language abilities. When I was at the early stage of English learning, movies didn't really help me a lot since I was mainly looking at the Chinese subtitles. Therefore you have to pay attention when you use soaps or other things like this to learn languages. ^^
Shows you can try:
《少年师爷》(easy)
《使徒行者》(moderate)
《法证先锋》(moderate)
《锋刃》(moderate)
《甄嬛传》(difficult)
All the above are attractive in plots. If you are interesting in romance plays, you can try these.
《同桌的你》
《太平轮》
《分手大师》
(Hope these will help. ^^)
