Best Sci-Fi series this season!

Like any good science fiction series, it starts with two episodes meant to introduce the characters. After that, you get some very interesting stories.

Capt. Ed Mercer is in some way a little bit like Michael Scott from "The Office US".
His Ex-wife and 1st Officer Cmdr. Kelly Grayson is very interesting. She's broken her husband's heart, but seems to still love him in some way. She's also very capable.
LaMarr and Malloy are a hilarious duo. They pilot the ship together and have incredibly funny conversations.
Bortus, who's got his husband in the ship, is a very dutiful officer with an interesting background and home life.
Kitan is a young bridge officer who only got the position as chief of security because people from her planet don't join the military often (she says so herself). She's extremely strong and can open any jar of pickles in the known universe (you'll get that after watching a few episodes).
Dr Finn has a humour as dry as Mars' surface. I'm surprised she's not British, she could very well be.
Isaac is the absolute Anti-Data. The president of his home world could be Skynet. His Android race considers any carbon life as inferior. And they don't mind telling you that. Isaac has taken the position on the Orville to study human behavior. Or their weaknesses. Like any artificial life form, he's got problems understanding jokes and slang. I like him and I don't fully trust him.
Last but not least, there's Yaphit, a jelly life form whose favourite hobby it is to annoy Dr Finn with his flirting.

So far, there've been great stories which got you thinking and had fun and action.
I can already see the potential for the development of more surprising and serious stories, running gags and maybe even some longer lasting story arcs.

You can see the love Seth MacFarlane put in this project. I'm not that often this enthusiastic about a TV series, but here, it's absolutely justified.

(No) Update after episode 6:
No need to update my review. The show just continues being great :-)

(No) Update after season 1 is finished:
This serial will become a TV legend like Star Trek TNG has become one. There'll be a time when fans will do fan fiction serials in the Orville's universe.
