I sat down to this with an alternative (DVD featuring George Clooney - it's not his fault he never met me first) to hand just in case, but loved it. As Dougie says, it could have been sentimental and even patronising, but instead it was very warm and loving. The bits where Neil himself, Macari and the other real people popped up to confirm that things really happened (or not) added to it for me: it would be very easy not to believe the story was true if they weren't there.
I do feel a bit cheated, though. I did a qualification at Keele in the mid 1990s (our ceremony was held in the chapel that featured in the film - most if not all of the university location shots were really done on the campus) but never heard of, let alone met, Baldwin. However, we were part time, distance learning students, so we were only there at weekends and in the holidays, when nearly everything was closed, and I guess he'd have been busy elsewhere.
