Not one of my favourite episodes at all!
The plot is weak, when not ridiculous (a dolphin that is gonna be used as a bomb??), the rhythm really low -they talk and talk and talk and do nothing- and the character of Goldie, Magnum's old acquintance, a little banal (a young ingenuous, candid woman with strong code of ethics but whose actions have often disastrous consequences...nothing new).
Really an useless and often boring episode: while "enjoing" it, I often caught myself looking at the clock, almost hoping it was over.
Watched it anyway -it's Magnum PI after all- but it definitely doesn't match up with the firt seasons episodes. OK, last seasons were of course sometimes weaker than the first ones, but this ep...only the shadow of what Magnum used to be.
