I was aware of tomb's discovery... and also the early claims of connection to Jesus. My understanding is that it has not been given much credence or weight. What most people do not know is that Jeshua (Jesus), Miriam/Mariam (Mary) and Josef/Josa (Joseph) are quite common names in 1st Century Jerusalem.
It would not be surprising to find such names on ossuaries in juxtaposition in a tomb.
As the article states, it is the film makers who have "made" the leap of identification. This is not the way science is done. I doubt any of the "scientists" involved would publish their findings this way. Look at the history of the cave and the time that has passed. Would any archaeologist of any stature allow his findings to be upstaged by mere documentary film makers? No way.
This is a modern day version of the 'fraudulent religious artifacts' industry of the middle ages. And gullible folks will be taken in now just as they were then.
