LICA's right, "nie podoba mi się" sounds a lot better. Mostly because "a situation" is usually something more short-term, so the 'first impression' thing would work better... although frankly, even if this situation lasted 5 years already, I'd still prefer "nie podoba mi się".

I can't change it though, because it's too early in the tree.

Added "that".

Ah yes, the good old negation. It got me again.
