I liked this episode. The parts you call sappy didn't bother me in the least. It wasn't like in the season 1 episodes Life or Earth. These folks are going into a deepfreeze for at least 3 years, possibly for over a thousand. It's quite natural for people to want to be able to say goodbye to the ones they are close to and about to leave behind. I'm amazed that you didn't catch on to the fact that Park had not been able to see anything for two weeks and may not be able to ever see anything again for the rest of her life. Suddenly being able to see again while in another person's body she visits a place she was probably fond of and spent time in the past so she can remember what it was like. Does anyone remember the scene in ST-TNG where Geordi Laforge wants to see the sunrise when he temporarily is able to see the way normal people do? If every episode were movie-sized then I'm sure the writers would have been better able to touch upon the emotional aspect of the situation but time is limited. I think they did a good job on it. It wasn't too long and not too short and the subject couldn't have been left out because that would have been ridiculous. I hate the friggin' commstones like no-one else but this was well executed.
While everyone seems to have a pick on Eli, I was happy to see he finally came into his own. It took until the very last episode of the show but finally his testicles dropped. Good for him!
The music in this episode was pleasing to me and I thought it fit the atmosphere well. Especially in the last moments of the ep when the lights were switching off sequentially which was by the way brilliantly done.
What I didn't like about this ep was that bullshit about Scott taking away his child from it's mother. That was completely ridiculous. He and the child had never even seen eachother. He's on the other side of the universe for about a year (the kid seemed older by the way) and he knows exactly what's been going on with his ex girlfriend because "she's not a good parent." Give me a break please! Also this came completely out of the blue as it hadn't been mentioned in at least a season and a half.
Another thing I found ridiculous was that they needed some material to fix the stasis pods and then they went to a planet to get it. They came back with a bunch of rocks and asked Brody if he could do something with those. And ofcourse he can. Problem. I haven't seen a friggin' ore processing plant aboard Destiny so far. Apparently Brody MacGyvered one out of a pair of socks he had been wearing for a year a piece of purple fruit and a worn down toothbrush. Also this stuff was supposedly highly toxic yet they brought it aboard Destiny as if it were candy and let people without suits handle it.
All in all I thought it was a good ep. I liked it. It was a fitting end to the show yet it still leaves open possibilities for the future. I'm not experienced with the American grading system but my feeling tells me I should give this episode a B+. On a scale of 1 to 10 I would give it a solid 8.
