Yes! I'd say Free Guy is absolutely worth the watch.
It's very light hearted, fun entertainment.
That said... well... let's just say it's not going to be winning any huge awards for poignant mind blowing content, or deeper heart felt explorations.
If you liked this movie, then I would say an even far better one that has a similar feel is the movie Boss Level.
That one has some very similar elements and tropes (yet covers a different SciFi topic), and seemed way more engaging and intriguing than Free Guy.
Also... for those liking Free Guy, but who have not yet had a chance to check out the TV series Upload then you're in for a fun surprise of a TV show!
