In that case don't worry, I wouldn't want to inflict TPM on anyone over 12 years old!I've seen all the main Star Wars movies - TPM to TLJ to me is like Windows 8 to Windows 10 - Windows 8 is dumb Windows 10 just takes the mick.
On the other hand it is almost 20 years since I watched the original TPM release I'm not sure what my opinion would be of it today to be fair - the last time I watched it was the fan edit.
I haven't seen the fan edit, nor have I seen the Despecialized versions of the original trilogy - I'm not sure I'd be able to spot the changes to warrant watching them.
