It's bad in different ways. The action, despite being full of CGI, is much more grounded and doesn't have the crazy over the top moments like nuking the fridge or swinging with the monkeys. But the writing is pretty terrible with major characters and story lines just getting forgotten, bad guys that can teleport around to show up whenever they are needed and character arcs skipping the actual arc and problems just magically resolving themselves.

Despite all it's problems I still enjoyed it, since you can kind of see there being a good Indiana Jones movie under all the problems. But it's really a mess of a movie if you think too much about it. Movie studios really need to start spending some of their hundred million budget on getting the scripts fixed before they start filming. Kind of inexcusable to spend $300 million and have the result look like it's held together by duct tape.
