The more I think about the exterior shots where the mom and daughter are in the canyon in eps2 being rained on... how were these shot with the water drops? Where the helmets entirely CGI?

Same with the water on the glass window in the same episode with Dr Smith sitting on the bench against the glass... the water on the glass was perfect, but could not of been keyed. Or could it have?!?

Keying and comping has come a long way. These VFX effects are seamless.

Now, if they spent as much time on the story. Sooo many plot holes. I try to just ignore them.
