I think the primetime special was very well done and respectful of the show's 50 year history, particularly the segment dedicated to Bob and especially Drew's comments to Bob. The way he spoke, it felt solemn, like he was very thankful to Bob (for hosting for the first 35 years and for giving Drew a wonderful job to continue), but also regretful that Bob couldn't be there and likely, won't ever get the chance to make a return appearance. It was very honorable and respectful.
I'm also glad they finally allotted a two hour block for a primetime special. I had been thinking of this since the Barker era. (The 25th anniversary special, the 30th anniversary special, etc.) When you only allow for one hour, you can do one of two things. You can use the one hour format (3 games, showcase showdown #1, 3 more games, showcase showdown #2, and showcases) and allow for a minimum of clips or you can use the 30 minute format (3 games, showcases) and allow for a maximum of clips. The two hour block allows for the one hour format with lots of clips, so I'm glad someone finally figured that out. Bravo.
Some have suggested that the original Price Is Right with Bill Cullen should have been acknowledged, but I think the reason it wasn't is because this was a 50th anniversary special, meaning 1972 to 2022. The Cullen edition aired from 1956 to 1965.
Overall, a wonderful special, but I would have added two things.
1.) a mention of Mark Goodson and his contribution to the show. Maybe show some clips of the times he visited the show.
2.) acknowledge the half hour, syndicated, nighttime shows/hosts. Dennis James (1972-1977), Tom Kennedy (1985-1986), and Doug Davidson (1994-1995). This could have been in place of the segment they did with the different editions of TPIR around the world. They could have done a brief explanation, showed a few clips of Dennis, Tom, and Doug and maybe even had a visit from Doug, since Bob was unable to visit.
