These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Open Season
Alternative Character Interpretation: Sure, Ian is a Jerk Jock. He's vain and pushy and a bully. But on the other hand he isn't a coward and he does seem to be a pretty good leader of his herd. And Elliot IS a loser and an idiot, and while we never find out what he did to be thrown out, it's pretty likely he did something.
Bizarre Sexual Dimorphism: Mild case. Obviously justified with doe/stag, but did you also notice how different Boog and Ursa look, snout-wise? (Blame it on cuteness factor.)
Ensemble Darkhorse: Buddy the blue porcupine. Also, Roger the mentally retarded cat. Alistair might count, too.
Nightmare Fuel: The scene in the first film when Shaw is looking for Boog in his cabin.
Then, there's Boog accidentally dooming the whole forest. The song playing during the montage afterward doesn't help.
Unfortunate Implications: In the second movie, which takes place a year after the first, Ian mentions that he has to stay and looks after the herd, then makes a nervous face. No herd is seen throughout the entire movie.
The Woobie: Alistair the llama from the 3rd movie. Boog from the 1st.
