Malaysian cinema is apparently going through a bit of a boom
Have you looked at Letterboxd? Its primary focus is films. Discovery (finding new titles) is harder there, unless you happen in to some good lists and contacts but the database isn't geo-limited in the ways devs have chosen for MDL. If you know the title already, it can be a great resource.
There are over 800 votes to add Vietnam but we just get the run around from devs, or ignored, so finding other resources for Malaysia is your best bet. If I could code I'd be building a SE Asian-focused site, but alas.
By all means, voice support for getting Malaysia into MDL's database. Just don't hold your breath or anything. Find other means.
