Very badly done. Spoilers

Tina was 15 when she met Bobby in 1958. This was depicted in the very first scene. The next scene was showing the prep for her wedding, but they gave no info about how much time had passed. That set the scene for the rest of the first episode. They gave no clue about the year, and glossed over important stuff, such as when Bobby refused to sign a new contract.
I'm none the wiser now about Tina and Bobby's early years than I was before I watched it. Awful
