yes, that is good news...for Paramount that may have a Trekkie for life to buy up their overpriced Trek products, watch their up-coming Trek films, etc. The younger you get them the stronger impression you can make upon them, and longer you can have a milch cow to leech off of.
When i was five i got into Star Wars. I didn't get into Star Trek until i was a teenager. That was because i couldn't understand Star Trek at five. I'm not sure what a five-year old will get out of Star Trek, they'll have memories of space and of things blowing up, going Kabooy! Good-looking young guys running around on a spaceship, and bad men in black with tatoos.
