I get that they wanted to show how much this group is unprepared for time travel, and how they'd muck things up on their first go-around. But they really should have sidelined Rip Hunter in a better manner. As the episode stands, it looks like he decided to hang around Waverider the whole time and sigh exhaustingly at every turn. Instead they should have had him shot at the end of Part 1 (by Chronos) and spend most of this episode in the Medbay or something.
It would have been neater if one of two things had happened: 1) Doctor Stein actually vaguely remembered meeting his future self and all the craziness that ensued (rewritten to make sure it wasn't too crazy) or 2) Rip admitted to giving the younger Stein some forgetting drug or something. Admittedly, the young Stein apparently did do a healthy amount of drugs, so maybe he forgot the whole adventure naturally.
I don't see why aliens wouldn't exist - although it is odd that only Humans appear to be the Time Masters. Maybe they're waiting to see if they ever get a license to reference Superman, or can fold in Supergirl or something before introducing aliens to their universe (which should be a pretty big deal). When the Legends inevitably go to the future, they should run into some alienesque activity.
