Seriously, what happned with Amy in Sonic Boom? They litterally sucked all the personality out of her character. I never liked Amy that much in the games, but I thought she had a good setup for a character, and if the writers tried, they could actually make her a really funny and likeable comic relief character. She was fine (for the most part) in sonic x, but in Sonic boom, she's just pretty flat and 1-dimensional, that doesnt really add anything to the plot(s). Yeah, you could say she's "sassy and independent" or something, but personally, that doesn't really make a strong character.
Not to mention, her design sucks
