Just watched Sunshine, and well, have to say, what the hell was going on with the end of that movie*? I can totally understand the criticisms of the movie suggesting it was little more than an SF movie that referenced other SF movies**. About the best thing I can say is that there have been few SF movies as pretty as Sunshine, the fx were gorgeous.
And the alternate ending, pray tell, how was it fundamentally different to the ending of the cinematic release?

*Sure I'd had a couple of glasses of merlot, but hey, that usually doesn't impinge on my comprehension of movies.
