I love it. Using the childish Lois at the beginning was a nice touch. And there were so many times I said "aw," both sweet and sad, but especially sweet. I think Ellen and Sam's hug at 1:00 was one of the best. All the couples hugging moments were sweet, though. And so was Jimmy hugging Lois.
I liked the usage of "tv" footage for the "no more lives torn apart." What's best is that we get to see Lois and Clark react to what they're seeing.
The "blind belief" - "truth" section at 3:25 was an example of beautifully matched lyrics and visuals. That is great for Lois' realization.
