This episode of "Philip K. DIck's Electric Dreams is nearly superb. I own that I only scored it a nine from the possible 10 because the pace is a little slow and the film is a touch dark for me. However, Cranston's performance impelled me to a nine because here is a 61 year old man who does a sex scene and it is believable.
Now for some disclosure: this sex scene does avoid frontal nudity of Cranston. However, his passion that seemingly comes through for me and Davis's reaction (the actress playing his wife) is 100% on target.
Some have negatively reacted to this episode in that Cranston and Davis are not passionate enough AND that this ending is unambiguous. Certainly, I disagree with the first assertion above and do concede the second. However, just because the ending is unambiguous does not limit the episode's effect on the viewer. I was as moved here as I was in "The Matrix" "episodes one and two. If a video effectiveness can be measured the viewers reaction, you have to acknowledge my score and you have to watch this episode and let the events happen (with a certain degree of Cranston's back story creeping in.
If you watch this episode with the guidance I have noted here, you will be moved and you will certainly enjoy this episode. If you allow a preconceived judgment shape your experience, then you will not like this episode as much as some of the others. So you decide and watch,
