Just saw it this week and I felt it was more of a stem cell embryo issue than just cloning in general. At the time in 2003 the whole cloning thing started rising up. I also felt the music cues were very strong. Especially the one where Sim goes to lay down on the medical table near to have the surgery. The audio commentary by first time ENT writer Manny Coto was very enjoyable. and nice funeral ending with nods to STII:TWOK ending. I thought the young boy's accent was great but the late teen-early 20s aged Trip (Sim) was too stiff and lacking the accent and agree with Manny's audio commentary on that aspect of actor selection. I see these other two Similitude (Dec. 2008) Similitude (May 2009) older threads but thought I'd start a new one. uh, oh...I haven't seen season 4 yet except the series finale... I hope season 4 is as good as season 3 has been. FYI I skipped seasons 1 & 2 after the pilot and first couple episodes as I heard they weren't that good. I'm watching ENT seasons 3 & 4 on Netflix.
