After reading the reviews I have sooo many questions... terrible movie

Rating: 1/10 (7 November 2018)

I like rom-coms. well to specify, I like good, funny rom-coms, I really don't think I ask for much when I watch one, so this is why I'm selective of which ones I spend my time watching, I'm a fan of both Bullock and Reynolds and think this movie was the worst thing imaginable they could've come up with,
But after reading the reviews I thought I may have watched a different movie because some people describe it as laughing hysterically, finding it sweet and heartwarming, great chemistry between Bullock and Reynolds (which I don't know how anyone can arrive to that conclusion when it's obvious that's what is missing the most, even from trailers you can tell they have - zero chemistry).
Granted I had my reservations about seeing this movie from the start since I didn't even like the trailers, but my wife wanted to see it and I'm a big Sandra Bullock fan so I said why not, maybe they'll surprise me.
I understand each perception is different, but it's not explained in the movie why they like each other all of the sudden, they just filled the time with cliche and cliche about a bunch of nonsense. All rom coms have this, but the chemistry is not there, they don't look good together, for starters she looks too mature for him and there's no endearment from either part, it's all scripted without emotion, thats my view I guess
So the movie people describe on these reviews is quite different from what I saw, so I have a few questions for anyone who cares to answer in another review:

What made you laugh hysterically ?? This is my biggest question because I don't remember laughing or giggling at all, at all, I'm not trying to be a stiff, I love comedy and I can find something to laugh about a lot of things, people love my humor but these comments have me baffled, I sincerely can't think of anything lo laugh about in this movie.

What sold you the idea that this couple had chemistry ? IMO they look distant and stiff around each other and when they get together it's all artificial, so what did I miss ?

What made you think this was a sweet movie ? Maybe I watched too many movies but all the "sweet" moments are copy and paste scenes from other movies, and the pasting Is pretty clumsy and predictable IMO, may be you have a better moment that tells you something.

If not laughing hysterically most reviews describe the movie as funny, what are the funny aspects of it ?

I'm sorry if I come off as a jerk or obtuse, is just that my wife and I hated this movie and we were discussing the other day about it and she told me "I bet people loved it", I said "No, I don't think so, it was terrible" and we made a little bet which obviously I lost, lol, so I found the time to write this for anyone who cares to read it before I go and pay my debt, lol.
