The Lake House has entertaining bits in it, as does Frequency (although to my mind that film starts brilliantly, becomes mediocre in the middle, and ends up as overly sentimental dross).

About Time I really need to see again. I saw it in the cinema and own the DVD, but I've yet to watch it a second time. I enjoyed it, but I think the death of my father the previous year rather coloured my ability to judge it objectively (I was crying my eyes out in the finale).
