LotR seems a few levels above to me – certainly the first one is in a different street to any of the HP films.
The ending of the books with the eagles is execrable, so it’s not like Jackson could do anything about that. Missing out Sharkey and the Shire seems inexplicable, although I’m sure he had his reasons – the ending he dished up has passed into bad-cinema legend.
I guess that LotR has such masses of world-building behind it that it’s always going to be under the microscope more than other film adaptions.
I like the HP films just fine but the acting is definitely a double-edged sword. The old luvvies (every last one of them on the books of equity, from the looks of it) bring some class to proceedings, but the child actors at the centre are dreadful.
