So as a hardcore fan of Stargate is have mixed feelings so far.

1. An episode is only 10 minutes long,
they have 10 episodes planned from what I can tell meaning it's 1 hour and 40 minutes long.
So this is a kind of movie split in to 10 pieces.

2. As it's about the 'Origin'
In the first 4 episodes I have seen quite a few mistakes about the Stargate us.
for example: The Stargate used in the movie they puke there guts out because our side has no stabilisers for the ride.
other example: activating a symbool requires it to be placed on top where it's locked, not at the position where a light is...

3. The acting is ...
Well the acting so far is below average expect for Connor Trinneer he is awesome.
But the rest of the cast are not really impressive.


Edited:
So I watched the full series... and I have to add a point 4..

4. The special effects
They are horrible, I have a little experience with special effects and I could do a better job then is shown in the series.

5. The end
So the series has a poor beginning and even in the middle of the series it's hard to follow anything because the
story is just boring but then the end... That's just hard to watch (I mean almost everybody dies in the end) that's not
the hard part. The hard part is how they try to wrap it all up and make it 'sound' like this is the reason why the rest
of the series have been made. (All the other series of Stargate...)

In universes like Stargate, like Star Trek, like Star Wars, there is a lot that is canonical. There are a lot of things that really shouldn't be changed, and a lot of things that people need to remember in order to make the story fit with the rest of the universe.

Unfortunately, like Star Trek Discovery and the Star Wars sequel trilogy, the show kind of takes everything that is canonical and completely ignores it...which is a trope for a lot of Science Fiction these days...and one that instantly alienates the fans that invested a lot of time, money, and love into the universe.

But what is worse than that is the production values are absolute crap...and this is Stargate we're talking about, this is, like Star Trek, a universe that never exactly attempted to make very convincing alien sets.

No matter what planet they went to on the series it always looked a lot like British Columbia.

The production value of this is even worse. It looks seriously bad.

And the dialogue makes little sense, even for seasoned Stargate fans...it's just bad and out of place.

And the acting isn't much better.

So, what you have is an extremely cheap, extremely low budget, horribly written and horribly acted attempt at making a Stargate addition that, well, that ignores a lot of what is canonical in Stargate, so even the diehard fans won't like it.
