This show is great escapism - excellent story, awesome cast and acting! It takes you to a world very similar to your real one, but there's this amazing thing happening - travel to other worlds. The main characters are complex, but relatable and the camaraderie that grows as the show continues is very well done - starts a bit stodgy and develops as relationships do with coworkers - the humor and interpersonal quips between characters is excellently executed. The shows storylines and some episodes also pose some interesting philosophical questions and theories, if you like that sort of thing. :-) It is good enough to re-watch many times over. Enjoy!
