Heartwarming / Tucker & Dale vs. Evil

• The You Are Better Than You Think You Are speech Tucker gives to Dale after the car crash and Allie's kidnapping. It gives him the courage to go get what he wants and save Allie.
• Also Dale and Allison's romance - it's a (somewhat) realistic depiction of why the Ugly Guy, Hot Wife trope does have validity to it, as Dale shows himself to be genuinely supportive of Allison's goals (vehemently declaring "Dreams are not stupid" when Allison says her goal is A Degree in Useless), and the pair have mutual interests due to Allison's own Hidden Depths.
• At the end Dale and Allison's bowling date, culminating in him giving her a pink helmet to prevent any further head trauma, not to mention their passionate kiss.
