There's a person I know who has the same opinion on everything. It never wavers from "very good" e.g.
That was a very good movie
Brazil played a very good game
The weather was very good yesterday
They're not really an optimist per se, as a term such as the one I'm looking for could easily apply to someone with the opposite "very bad" opinion of everything.
What I'm wondering is there a particular term for someone who has the same opinion on everything?
This is a similar (but not the same) question, and although some of the answers here (such as yeasayer) could work in certain contexts, they don't fully answer my question.
