It may be related to a contrast between American English an British English. American English speakers will often use adjectives in place of adverbs when speaking colloquially, e.g. "That tastes real nice" instead of "That tastes really nice". The same is the case with "good" and "well". This does not usually happen in British English, other than by modern American cultural influence.
