Much fuss was made over the announcement of a second season for Marvel's recently released Daredevil Netflix series. Given the series' mass critical acclaim and wide viewership numbers, a second season was something of an inevitability. But the fate of Marvel's Agent Carter series is much less of a certain thing. In spite of its wide critical acclaim (it currently ranks at 97% approval rating on Rotten Tomatoes), the show pulled in underwhelming ratings, with surprisingly few viewers turning out to watch as the series went on.
The low viewer numbers led many to think that a second season was unlikely. Recently however, many websites have stated that a 2nd season is seeming more likely. And now, star Hayley Atwell has added fuel to the fire! At the recent Chicago Comic and Entertainment Expo, a hand-written 'frequently-asked questions' note was pinned to her autograph stand. It read 'We will know in 3 weeks if 'Agent Carter' is renewed for another season. But it looks good given the fan response.'
