I didn't find Die Hard 4.0 to be that bad, but A Good Day to Die Hard is pretty mediocre and not worth watching again, if at all. Right from the start it felt boring and the plot feels lacking. It tries to wow you with car chases, gun fights and explosions but it comes out as trying too hard. The twenty minute car chase felt far too long. It doesn't help that it's situated near the beginning where you don't know what is happening so you can't really invest into this car chase. You only know is that some guys are there to kill the prisoner, not enough reason to give you rooting for the protagonists at this point. Once the plot does get revealed, it's something that's been done many times before, in the end, it's really simple too, it's pretty much just an excuse to string together one gun fight after another. It actually felt disappointing, and then they had to include the whole father and son subplot which is annoying and not needed at all. It's a sad fact when even the gunfights feel boring and lacking. The climax takes place at Chernobyl, yup, that radiation filled place and in the end, no one wears any sort of protective equipment (antagonists do... for the first part but then they take it all off since they somehow got a compound that neutralizes radiation, riiiiiiiiight). The movies makes it seem like the protagonists and antagonists are douches and every single action scene feels too implausible to survive.
