I just watched "Turn Left" on SciFi last night. In general, I found the deletions to be fairly minor. However, people might want to know that the Sontarans were defeated by Torchwood -- all died but Jack, who was transported to their homeworld, and thus for all intents and purposes was gone. But that was the only deletion that seems worth commenting on.

*I* want to drink alien bubble tea with the Doctor.
Also of note to SciFi viewers: "Journey's End," Part 2 of the Season finale, will air on August 1st at the earlier time of 8:30pm. The episode ran to 1:03:03 on BBC-1, so SciFi is giving it a 90-minute slot.
