There has been sightings in the woods near Roswell and the gang decides to go camping there with their dad as an opportunity to enter the area without alerting the authorities and investigate these sightings.
Max and Iz's dad is no back but with a different face. Seriously, for some reason they had to recast the father and now here he is.
This episode is very entertaining, the Liz/Max scenes as well as the Alex/Iz scenes have their moments. Liz's father investigating her was... well pathetic and I'm not sure this had a purpose at all. Oh yeah right, he realizes his baby girl is a woman now. Big deal, I want to know where Max is from and this theme with Liz is approached again a few episodes later with her mother.
Anyways, interesting episode.
