(Edited to add: I didn't realize that this comment would end up on a new page, but I am kind of following up on what LuvMyShows was asking us all near the end of the previous page, as far as what we like about Hallmark.)
I know exactly what I am getting when I watch Hallmark movies (romances, Christmas movies or mysteries). I know what to expect. I appreciate the formula and predictability. I don't need anything deep and meditative from my Hallmark movies. I don't need incisive studies into the human condition in my Hallmark movies. I don't need a lot of "reality" in these movies either. I suspend disbelief and just enjoy them for what they are.
I like rom coms. I like seeing people faux-fall in love. I like seeing people celebrate the holiday season with snowball fights, gingerbread-making, snowman-building, tree decorating and caroling in charming towns. What I am tuning in to see is exactly what I am getting. The movies are harmless, cheerful, lighthearted fun.
I watch many things across multiple channels, so I don't only watch Hallmark and I enjoy a variety of content. If I am not in the mood to watch rom coms or romantic dramas, I just check out for a bit, watch something else and then start watching again at some later date. If I don't feel like watching a mystery, I don't watch it. If I am not in a Christmas movie state of mind, I don't watch. But, in general, I am a fan of the overall Hallmark or Hallmark-esque content and the kind of escape it provides, I suppose.
Now, are some movies within the genre better than others? Of course. But that applies to any genre on TV, as well as to any theatrical releases as well (not all epic disaster movies are on the same level, for example). At the end of the day, who really cares if this baking competition movie is better than that baking competition movie? It's a nice treat if one of the movies happens to be really good, but if it's not that great or if it's just so-so, then I move on to the next one. I have found that I end up liking some movies more if I give them another chance anyway, so what doesn't impress me now might be something I love in 2 years!
