Classic screwball comedy cut from the same cloth as the classics like Bringing up Baby or My Man Godfrey, but I think it's lack of popularity is due to two things.
1. It was released in 1950, some time after the "screwball comedy" popularity had waned
2. Most prints of this movie are pretty poor quality
The Internet Archive has a couple copies of this movie available for download for free due to it's public domain status and they are quite watchable but it's not not as crisp of a picture as you should have from movies of that time frame.
Some of the reviews complain about the plot, four veterans "playing the system" in order to avoid work, but that's what makes it a "screwball comedy", the plot lends itself to the hijinks that the characters are involved in.
Personally, I enjoy these types of comedies and if you're a fan of movies like My Man Godfrey, It Happened one Night or early Cary Grant films (Bringing up Baby, His Girl Friday, The Awful Truth etc.) then you'll likely enjoy this as well. Same zany antics and colorful characters with some tender moments driving the story along. It may not be at quite the same level of quality but still enjoyable.
