The Mandalorian, first two episodes out now

He probably didnt received much training since the Empire probably didnt allow Mandalore to have an army

What's the retarded thing?

Haven't watched the second yet but I felt that with the first episode that nothing much happened, bountyhunter gets his target, something something with 2 animals, some shooting with a droid, the end.

With Star Trek (well maybe except Discovery which was the Michael show) it was always around several people, i think it could be a pitfall if you have a show that is situated around 1 person.

In my opinion both parts was similar. Maybe first was more interesting because it was something new + contract negotiations and more words used (in ep2 there was very little of talking ;) ). But to be honest in both not much happened. It is caused by short time (30 minutes episodes witch is lower then average tv series) + they try to extend "action" (or rather slow tempo + work with a camera) <-- if you will try to describe the story of 2 episodes (1h of time) there are not so much to explain :).
To be honest I saw what kind of tv series it will be after 1 episode, but anyway I will watch it as I like sf settings and movies/stories anyway.

And about retarded space travel. Not sure what you mean, but you have to remember that Star Wars is more like a fairy tale in sf setting (more fiction less science comparing to average). You can not watch it and be totally serious about some things. But if you accept situations when you can repair totally broken ship with some random person then everything will be possible (by retarded you mean this thing or some other? - if this I can agree that in this situation it is a very fairy-tale setting but if you look on movies it is also inside StarWars setting :) ).

Baby Yoda is my new favorite thing
