Just to run it into the ground, Four Weddings & a Funeral was a Best Movie Academy Award Nominee, and pretty well received Stateside. In fact, my wife and I had a brief period where we watched it at least once a month for two years.
I've always cringed at Andi McDowell's performance, though. Always will.
And, just as someone noted hating Julia Roberts in Notting Hill, I want to add that I thought Laura Linney was atrocious in Love Actually. I liked Love Actually, but her part... maybe it was the fact that she had the least happily resolved of all the romances. I don't know.
Or, maybe, Mike Nichols can't direct American women. (American women were the weak links, performance wise, in 4 Weddings, Love Actually, and Closer.)
