Finally getting around to watching my least favourite Farscape episode - the second one filmed, - "I, ET", and a good candidate for "worst second episode of any sci-fi show". It's not *terrible* but it's such a tone shift from "weird aliens" to "sitcom humanoid hijinks" that it really derails the whole thing
but I'd forgotten that as well as being a riff on E.T., it's also obviously a riff on Contact.
Even down to the kid being named Foster, and his mother looking very like Jodie.
