Fan boys love spoilers. It’s part of the culture now to know the movie before you see it.
He saved old trek fans money and good memories. I thank him.
Spoilers are a complicated subject. The premise of GROUNDHOG DAY was spoiled in the posters at the theater, yet it's played like it's a big surprise.
OTOH, the best moment of the "New Star Trek" for me was the movie trailer, which showed the motorcycle chase without identifying the movie, so I got to be surprised at the end of it, as they blazed STAR TREK across the screen ... that was great. Note that the movie itself spoils the outcome of this scene.
