In einem interessanten Artikel über die neue COBUILD English Grammar geht es u.a. um die progressive form von stative verbs:
It soon became apparent that the situation with stative verbs is not as straightforward as it might seem. We wanted to capture this in the grammar, while not being excessively complex, so while we do give the general rule about certain verbs not being used in the progressive, and list these in the reference section, we also show that with some verbs (forget, guess, imagine, lack, like, love, remember and want) – you actually can use them in the progressive form, especially in informal language.
Außerdem geht es um den Gebrauch von much in positive statements und generic pronouns and determiners.
