Spectre was good besides these two things:
The 'brother' thing. It was stupid, but they wanted a personal connection between bond and his arch enemy. i just think they tried too hard to connect him with the previous movies.
The end: shooting down the helicopter. lazy writing. they could have thought of something better.
other than that, it's an average to above average bond movie. it felt more like the older ones with the formula and added humor, but didn't go overboard making it cheesy.
I think most of the hate for it is unwarranted.
