It's like asking if you like television. There a some good sequels, there are some bad sequels. And then there's Aliens, which is the best sequel.
It's just that any time a sequel is announced you see a bunch of people saying ''Oh no, not another crappy sequel'' so I just assumed that there are some people out there who out right hate sequels, without giving them a chance.
Maybe if the movie is bad in the first place or a sequel might not appear to be necessary.
