These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Super 8
Crowning Moment of Heartwarming: Joe and Alice have many of these, particularly when talking about Joe's mother and when the two hold hands in the final scene.
Hardly exactly the same, but it's really very similar to Cloverfield (produced by J.J. Abrams) in a lot of ways.
Considering that the entire movie is a splicing together of Cloverfield, E.T. the Extra-Terrestrial, and The Goonies, this could be said of the entire story. Though, YMMV on whether that makes this film a nifty homage to the films of Abrams' childhood, or an awful checklist of cliches from better movies.
Other than the scenes toward the end where we see the alien in fullnote Shared between ILM, who did most of the effects up to this point. And Pixomondo, under ILM's supervision, there doesn't look to be a lot of conspicuous CGI. Which is actually damn good work.
