The time frame that the show is set in is between the original TRON film and the 2010 sequel TRON: Legacy. The visual style and music cues are more along the lines of the latter.
The 30-minute "Beck’s Beginning" episode, that Disney XD was kind enough to provide a HD (720p) version of on YouTube, really gives us a good idea of who our main characters are going to be in this series. They get us right to Beck as he's on his journey to save programs from the tyrannical rule of Clu and his second-in-command, General Tesler.
Now instead of spending anymore time giving the full blown review, I'll let you take it all in for yourselves. Here is the full prelude episode of TRON: Uprising entitled, "Beck's Beginning."
I'm very pleased that the show retains a pretty serious overall tone, treating the material with the same sense of sci-fi drama that the films are known for.
Even though there's a very short opening scene in “Beck’s Beginning” that features Flynn’s Arcade, the entire TRON: Uprising series will be set on The Grid, following Beck, Tron, and this core group of programs prior to the events of TRON: Legacy.
TRON: Uprising stars Elijah Wood in the lead role of Beck, and he is backed up by a very impressive supporting cast including Lance Henriksen, Mandy Moore, Paul Reubens, and Bruce Boxleitner as TRON.
The Disney Channel will be airing “Beck’s Beginning” on May 18th and the official TRON: Uprising series premiere will be on June 7th at 9:00pm on Disney XD.
