The first one was an integral part of my childhood and is still a very fun movie.
The second one was totally inferior to its predecessor, but still quite fun. Doesn't deserve a lot of the hate.
This one has a lot of conflicting emotions for me. Can it be close to the quality of the first movie? It took a decade to make, they must have thought about how to make it perfect, so hopefully, yes. But its a sequel, and most sequels are pretty bad. Time travel can be such hit or miss...but there's an 8-year-old inside me who wants to blow up some goddamn aliens and no feelings of cautious optimism or apprehension are going to get in his way.
