Absolutely amazing this is by far the best sequel and best film i've seen for a long time, there are some gripes Ackroyds a bit wooden and it luls quite a bit at mid point, but only for like a few minutes and i feel this lul was because so much of the rest of the film is so full of both nostalgia and and character building that that part felt a little empty, you'll know it when it happens.
The end is what you get from the Reitmans being good friends with the Ramis family, not saying anymore. but this is as good as we are ever going to get and i wish they'd leave it there now.
Also i cried like a baby a movie hasn't made me do that for a while
