This line is normal (the list contains 5 strings):
143 ['The Bridge on the River Kwai', '1957', '161', 'tt0050212', '8.2']
This line is not normal (the list only contains a single string):
144 ['Lock, Stock and Two Smoking Barrels;1998;107;tt0120735;8.2']
You should look at your CSV file (in a text editor, not a spreadsheet
application) and see what is different about the "Lock, Stock" line
compared to the "River Kwai" line.
