Ina Ka is quite good; it is in fact Hammi Sotto's favorite Lino Brocka film and I think the best thing Butch Dalisay's ever done. It's the middle-class version of Insiang, and being burgis, it's cooler, less vicious, more complicated (because they're more civilized). I don't think it's on the same level as Insiang myself, but it's definitely one of Brocka's better films.
Bona is available somewhere, I just haven't been able to track it down.
Oh, by the way, I finally, finally saw Mario O'Hara's Bakit Bughaw ang Langit, about Nora as a mistreated young woman and her relationship with a retarded man, played by Dennis Roldan.
To put it bluntly, it's a tremendous little work, one of the most beautiful Filipino films I've ever seen, and one of Nora's best performances. I can't believe a film like this attracted so little attention. It blows a Hollywood effort like Rain Man right out of the water.
I'd write more, but I need to digest what i saw a little.
pinoydvd, would you or anyone else know if the film was commercially successful? I doubt it. But this film deserves to be considered one of the best of the '80s. At the very least.
