I kind of agree, simply deciding to make everything look like film is often just ‘because film is cool man’. 24p is less frames per second than 50i so it looks a bit jittery when panning. This jittery thing is a look that is associated with film so stylistically people may like it but technically it could be argued as inferior.
However the film look can be very useful. Couple of examples are are
1) End credits with credit roll. I have a shot of a couple of musicians playing and a credit roll over it. Darkening the image makes the text easier to read and doing this with a high contrast film look gives something that looks nice and is dark. Rather than simply looking under exposed.
Another example is flashbacks, film look may be a good visual way of showing flashbacks.
