There really isn't really isn't any way to word this question that it would be considered separate from the FAQ question unless it was made a list question which are also frowned upon.
Though I can certainly see why you didn't feel satisfied with it, that question is a bit lacking in specifics on how to find the movies with those resources and I'll try and work out some more in-depth "how to use IMDb" answer for it later, but here's a preview which deals with your case:
You could try Lists, they're user made, but they have tags and you can filter them. An example for your case would be Lists tagged 'feel-good' which has 19 lists, and once you go on an individual list you can sort it by IMDb rating (user rating), or MOVIEmeter (some combination of user rating, IMDb searching and web hits):
