In the past, TV series from the 1980s to the 2010s were typically produced with budgets of $60-70 million per season. Because they typically had more than 20 episodes per season, they were typically produced with budgets of $1.5-2 million per episode. Therefore, Brad Wright and his team likely received a lot of "no" when they were making Stargate SG-1 and other TV series when they wanted to do something that required a significant budget. Nowadays, most streaming services, with a few exceptions, including Prime Video, focus on producing high-budget TV series. Video is said to be using all the technology developed in the last 14 years (presumably including the "StageCraft" technology used in The Mandarin. This is quite expensive technology, and after shooting the scenes with "StageCraft," they will re-edit all the scenes with CGI.)
