I find them to be a waste of money, as well as a depressing event altogether.
Well how do you know if you've never attended one? Yes, you may have a perceived image of how the ceremony proceeds, but not of the atmosphere or how you feel, which can vary quite a lot. A child's funeral will always be depressing, but if it's for example your long ill grandmother you can feel relieved that she's finally allowed peace. My aunt has Alzheimer's, and I don't expect her to be around for more than 5 years. To boot, she refused the medication herself, and has on occasion exposed a rather nasty and racist side of herself. But I see myself as her grandson since she never had any children of her own, and I'm going to attend her funeral.
Of course things vary to a massive degree with an issue like this (example: http://www.click2houston.com/news/familys-brutal-obituary-for-galveston-man-raises-eyebrows), but I'll be brutally honest with you: yes, I would resent you for not attending a funeral for the reasons you laid out. Since you've never had someone in your close family pass away yet (lucky you) you don't know how it feels when those people are gone forever from your life. Funerals are a way to gain some degree of closure with them, as well as giving them a collective sendoff.
And even if you basically knew nothing about the person and met them like once every two years, you can always just take the opportunity to socialize in a more dignified setting (well, mostly). And there's usually cake.
But then again, I have a very small family tree on both sides, and haven't been to a funeral since I was 10. For someone with dozens of aunts, cousins etc. I can see how constant funerals might be wearisome.
