The evil chick in the gothy outfit who makes a lead character turn evil happens in Inframan, which also has a lot of monsters.  Parts of it take place in an underground lair, as well.  There's not a blonde kid that I remember, though.

Parts of this remind me of "Wizards of the Lost Kingdom" but other parts - not so much.

not the awesome inframan or wizards of the lost kingdom i remember it had good production values similar to legend lots of orange and mist and Victorian era i thought it was a couple of hammer movies but wasn't them either its really driving me insane its probably a obscure european film thats lost to time lol
