Why doesn't this regex pattern parse the string "Season 02 Episode 01" properly?
For example, this is not a match:
var fileName = "Its Always Sunny in Philadelphia Season 02 Episode 01 - Charlie Gets Crippled.avi"
// Regex explanation:
// Starts with "S" and can contain more letters, can continue with space, then contains two numbers.
// Then starts with "E" again and can contain more letters, can continue with space, then contains two numbers.
var pattern = @"S\w?\s?(\d\d)\s?E\w?\s?(\d\d)";
var regex = new Regex(pattern, RegexOptions.IgnoreCase);
var match = regex.Match(fileName);
