a Thorny Third
Having married; siblings Christopher (Jason Lewis) and Cathy (Rachel Carpani) now live nearby to the abandoned Foxworth Hall where as children they were kept hidden in the attic. That attic and the house still haunts them and now their own children Jory (Jedidiah Goodacre) and Bart (Mason Cook) are finding themselves intrigued by the house especially when they discover that the vacant house is no longer abandoned as someone is movie in. That someone happens to be Corrine (Heather Graham) the grandmother they know nothing about who along with he man servant John Amos (Mackenzie Gray) seem to have some sort of ulterior motive for returning as young Bart is given his great-grandfathers journal.
So "If There Be Thorns" is the third movie in the "Flowers in the Attic" series with the first movie being all about Christopher and Cathy's imprisonment in the attic, the second movie was about them coming to terms with their incestuous relationships. In this third movie we get some time spent on the continuation of Christopher and Cathy's story as they try to keep their true relationship secret whilst still tormented by the memories of their childhood.
But the real focus of this third movie is on Bart as thanks to him getting to know his grandmother and reading the journal of his great-grandfather he becomes controlled by his extreme spirit. The thing is that "If There Be Thorns" is more in tune with the first movie with Heather Graham turning up the sinister and everyone deliver that touch of over the top to make this a movie which keeps on grabbing your attention even when it all seems a little forced. I suppose in a way it does a good job of going through the motions as it tries to recapture the spirit of the first movie but it doesn't linger in your memory.
What this all boils down to is that "If There Be Thorns" probably will be entertaining for those who became hooked on these movies right from the start. But for those who weren't it ends up just average entertainment.
