Anyhow, there really were serious problems in building L.A.’s still majestically insufficient, extraordinarily expensive subway system, but there was a lot more water involved than fire in the first seriously fouled up attempt at the important goal of creating some decent L.A. public transit in the City of Angels. Still, who wants to see a movie about busted water mains and overflowing sewers. So, instead, we got “Volcano” – from the director of “L.A. Story.” Seriously.
