Exactly. I think you can hand wave most things, and invent your own rules for how the universe works, including magic, aliens, FTL travel, teleportation, resurrection, etc. But there needs to be at least a cursory hand waving, and the hand waving and the resulting rules must be logical and not contradict each other. Although hand waved premises can set up the plot (magic exists and there is a school for magic kids) it's not really fun when the plot is advanced by hand waving new things as they are needed, and the hand waving should preferably just be background things like moving from a spaceship to a planet or walking around in space - in a budget friendly way. I personally have a problem with anti-gravity spaceships, unless the other technology is at least Star Trek-, Star Wars- or preferably even Culture level.
