Bernie was an all around solid movie.The thing that stood out most about Bernie was the acting. Jack Black played his role perfectly (and was also a surprisingly good singer). Matthew McConaughey also is great in his role. The movie was very interesting and enjoyable to watch all throughout. The movie brought much sympathy to the real-life Bernie Tiede and helped a lot of people understand what he was like. Overall good movie topped with incredible acting.
Watch it if you enjoy Jack Black. Avoid it if you want to see a really good film.
The argumentative dialogue lacks any sort of depth and the acting is unimaginative, with both Black and McConaughey bringing nothing new to the table other than their own, fatigued by now style when, unfortunately, MacLaine alone can't carry the whole film on her shoulders.
Do keep in mind that the "comedy" tag attached to this movie is terribly misleading as there are no real funny moments, with most of the humorous attempts being in extremely poor taste given this is based on a true story and they are afforded in the expense of an old woman who got murdered simply for being unpleasant.
Proceed at your own risk.
4 stars out of five.
