It's necessary. We needed an epic, foursquare, conventional Jose Rizal films (this and Gerardo de Leon's Noli Me Tangere and El Filibusterismo) before we can have the less conventional versions--Gerardo de Leon's Sisa, Mike de Leon's Bayaning Third World, and my personal favorite, Mario O'Hara's Sisa. Construct before deconstruct.
Not a big fan, but I do admit this much, it's an important film.
