Katrina never improved her acting or language. Her hardwork lies somewhere else. Mostly body and dance IMO and networking including dating biggest stars.
If she was so hard working she would improve her acting and language.
Anyway the discussion is not about her. One can name any artiste, film or song one thinks is more of luck than merit or quality.
Among singers I would add Mika who is shit. But clicks as audience has no sense of quality.
