of the series—the push-pull between Fey's character, Liz Lemon, the harried head writer of The Girlie Show, and Alec Baldwin's domineering network executive, Jack Donaghy—that 30 Rock found its rhythm." Henry Goldblatt of Entertainment Weekly, whilst reviewing the DVD release of the season, called 30 Rock "[the 2006 –2007 television season's] finest sitcom". Goldblatt said that the episodes "Hard Ball" and "The Break Up" were "some of the strongest episodes", and awarded the first season an "A" grade. Christopher Monfette of IGN thought that season one was "well-written and hilariously-performed" and that it was "refreshing to travel through the season and watch these characters grow and evolve". Monfette gave the season a score of 8 out of 10. UGO Entertainment's Kyle Braun said that the season "didn't start out as the funniest new show of 2006", but he praised the seasons progression, proclaiming "now that the show has found its audience, it's hard to argue with the laughs thrown down from high atop 30 Rockefeller Plaza." Anna Johns of TV Squad said that she was "particularly excited for the later two-thirds of the season, when Tina Fey and Tracy Morgan got into their groove and the supporting characters started getting better story lines."
