The scene where she jumps back on the ship (after Zane and Leo put her on the lifeboat), as unreal as it may be, was awesome. So was the one with the final goodbyes. And Rose passing on ("an old woman, warm in her bed" as Dawson predicts) and reuniting with him with all the dead people looking on - ideal ending as well. (About 11ty billion times better than that alternate ending with Bill Paxton's character confronting Rose as he catches her trying to throw away the diamond - seriously, worst alternate ending ever).
Yeah, that movie had its moments.
