It was a favourite growing up (up there’s with Explorers, The Goonies to me back then), I hadn’t watched it in decades till a few years ago. I also thought it held up really well. Besides the exterior spaceship there’s minimal effects anyways (plus cute aliens of course which were practical) it’s more an odd buddy (new friend?) comedy. I still thought what was there was for the ship effects held up better than expected for the time.

Course may be rose tinted glasses and all, but I really enjoyed it last time still, plus time travel is always awesome.
