What? What was this about? The other three episodes I've watched have been either excellent creature features or supernatural allegories but "Buddyboy" is definitely not the first, and if it's the second, then it's too deeply hidden for me to have connected with.
Dave (Martin Shaw doing an unidentifiable accent) is interested in buying a run-down Dolphinarium and converting it into a porno theatre as part of his business empire. The seller, Mr Hubbard (Wolfe Morris) is skittish and desperate to both get away and get the property off his hands, but Dave suspects he might have mob connections, so is unwilling to proceed. That is until he meets Lucy (Pamela Moiseiwitsch) a young vulnerable woman who used to work at the Dolphinarium and who tells him about the places star attraction, a Dolphin named Buddyboy, who died in unusual circumstances.
Whilst I do like my entertainment to sometimes be a little esoteric "Buddyboy" is too unusual and lacking in follow through, to make it worthwhile. The performances aren't good, from any of the actors. Shaw makes some very odd choices, not just in the accent but in the times he gets unusually angry and shouts his lines, or sneers at Jimmy, his associate - played by Stuart McGugan. Lucy, is played in a way you'd probably describe as having learning difficulties today and it was pretty uncomfortable when Jimmy kisses her, and in the later sex scene between them.
But it's the story that's the real problem, the jumbled mix of ideas that meanders to a conclusion which isn't explained. There's a theory proposed that Hubbard abused Buddyboy, prior to his death, which leads to the idea that he's haunting him, although this doesn't manifest itself in any way other than the occasionally noise, so it's hard to take seriously as a threat. There's also no explanation as to why Buddyboy would be involved in the actions of the final moments either or why he would be targeting Lucy.
There's the kernel of a story here, maybe if you refocussed it about abuse that Lucy has suffered, rather than the Dolphin, that might makes sense...but the actually presented story is a bit of a mess.
