Very enjoyable to watch. I can bingewatch this all night. And yes, Dr. Smith is someone you actually start to hate and sometimes wish she gets eaten by some alien however i guess they did a good job they can make you really hate a character so good casting. Every mark below 6 doesn't make any sense but i expect that to be kids that expect an all action sci-fi show like there are many and this is more of a family / adventure / sci-fi kind of show but that doesn't make it a bad show just another genre.
