My mom passed away almost 4 years ago, and I am wanting to honor her at the wedding. I plan on doing a set up at the ceremony site with her picture, candle etc; I am also planning on showing a video during the reception (on a 90inch screen) that I am having professionally made of my mom and I, since I was a little girl up until the most recent photo of us. I know that it will mean a lot to me, but is it too sappy/depressing? I know that sounds horrible me saying that, because honoring a loved one should never come off that way, but this is also a day of celebration, and I don't want to make my guest feel uncomfortable. Any thoughts would be greatly appreciated!! 
Also, we are having a second video later on of me and my fiance. It'll show pictures of us as kids and growing up, to coming together.. Basically how we got to where we are now. I don't if that helps at all. Thanks again!
