How much does one have to see...

As a little experiment-I wonder if I can generalise a film-from just 2 minutes viewing time. I saw 2 minutes of this on the TV last night, and it seemed like the most forced and unnatural comedy I've ever seen. I turned over.

Afterwards I thought-maybe I should have stuck with it-its got some great performers on it and a good director-Chris Columbus.
Was I right?- Or, is it worth sticking with-its on again tonight.
